I am receiving one of the following error messages. How can I resolve this issue?
Undefined function or variable ‹Name›.
Unrecognized function or variable ‹Name›.
Undefined function or method ‹Name› for input arguments of type ‹ClassName›.

MATLAB does not recognize the specified string as the name of a function on the MATLAB path or as a variable. "Undefined function or variable" can be caused by:
1) Trying to use a variable that has not been defined before this line of code executes.
>> x=1:10;
>> t=x.^2;
>> plot(x,y)
Undefined function or variable 'y'.
% Possible corrections:
% Change line 3 to "plot(x,t)"
% or change line 2 from "t=x.^2;" to "y=x.^2;"
2) A typographical error when typing a function or variable name. However, later versions of MATLAB try to resolve these typos with “Did you mean” suggestions. For example,
>> foo = 42;
>> fo0
Undefined function or variable 'fo0'.
Did you mean:
>> foo
3) The wrong case for a function or variable name. Later versions of MATLAB try to resolve these typos with “Did you mean” suggestions.
4) Changing directories so that a function you used is no longer on the MATLAB path.
5) Trying to use a function for which you are not licensed or that belongs to a toolbox that isn’t installed. In later versions of MATLAB, this is not an “Undefined function or variable” error, and MATLAB lets you know that you are either not licensed to use the function or the appropriate toolbox is not installed.
6) Calling an object method without an object as the first input.
7) Using a MEX function that is compiled on a platform different from the one in use.
8) Trying to use a function that has been removed from MATLAB. In later versions of MATLAB, this is not an “Undefined function or variable” error, and MATLAB lets you know the new, preferred function to use.
Solution:
  • Verify that the undefined function or variable is visible (it is on the path or in the current workspace) and that it has been defined before this line of code executes.
  • If you are certain the variable or function exists, verify the case of the function or variable name. If the undefined identifier is a function, the 'which' function can help you verify that it is visible to the function where the error occurs.
  • If you are having problems with your MATLAB search path, run the following MATLAB commands and then restart MATLAB:
>> restoredefaultpath % This will remove any custom paths
>> rehash toolboxcache
>> savepath

In addition to the Mathworks list:
9) You might be trying to use a variable that has been cleared.
If your code includes
clear all
or
clearvars %without the name of a variable
then you should probably get rid of those statements from your code.
If you had those statements in order to prevent old variables from interfering with new uses, then you should probably be rewriting the code as a function.

Undefined function or variable 'shaperead'. On the description page for this function it says "Introduced before R2006a". I use MATLAB R2015b- academic use. Does that mean that the function is not available for student license? How can I perform this kind of check in the future? Many thanks, Alex.

Type "ver" into the Matlab Command Window. shaperead is part of the Mapping Toolbox, if you dont own it you cant use the function. Normaly it should be included in the academic license, so check if you have downloaded it. If not you may try to load it.
If its not for free in your version you may try to contact your IT so it can be included into the license.
Otherwise, if you have newly created the code try to restart matlab once, sometimes that helps, too.
Best regards

Undefined function or variable 'lgemri' when I enter the following:

The nrrdread function has been taken from the matlab file exchange: https://www.mathworks.com/matlabcentral/fileexchange/34653-nrrd-format-file-reader

Same error but using a Mathworks example. Here's the contents of fact.m
function f = fact(n)
f = prod(1:n);
end
Located here:
/opt/software/MATLAB/2018a/toolbox/local/fact.m
When trying to use:
>> y=fact(5);
Undefined function or variable 'fact'.
I cd'ed to the directory containing the file before starting MATLAB and it's in the search path:

Any suggestions?

Do not store your own files in a directory under the matlabroot directory. See this documentation page for some of the reasons why. If you must do so, that documentation page will also tell you how you can.
Consider storing your files in your userpath folder instead.

Something strange is that when I try to call some function from toolbox (communication) I'm getting that it is not existing.
Even when I'm going to %MATLABROOT%\toolbox\comm\comm where the m file is existing, I still can't run it.
Please suggest what is the issue

I have seen this issue before with other functions. As stated before, first check that the function name is spelled correctly and that the function is located in the matlab search path. Assuming those two things check, then delete the path where the function is located, then reset the path. I would also will restart Matlab. I'm not sure why, but this seems to correct the problem.

Hello !
I have a matlab function which at a certain point calculates sin(2*pi*freq*t_array) (t_array in an array of size (1,2000).
I tried to call this function via matlab.engine but I got the error message: "Undefined function 'sin' for input argument of type 'int64' "
I wanted to add the file 'sin.m' to my working directory but it is not a function script, it is a simple text.
I would be very grateful of any help
Thank you !

Help!
I received "undefined function 'string2char' for 'char' type input arguments".
This error occurs only when I use mphload('filename') in an exe file. When in a .m file this line works well. I thought maybe mphload use 'string2char' function whatever its input argument type is. I use mphload("filename") instead. It still doesn't work...

Hi all,
I've had this error after a newly created function would give this error even though it was in the correct path and was user-defined (so no problem with needing the correct toolbox or licencing).
The name of the function and the file name you save it as MUST BE THE SAME.
I had saved my function a different name and therefore gave this error. This tip isn't in the accepted answer's response so give this a try.

I have a probelm:
I have a list of varibles defined at the top of my script but when I am trying to create a function the defined variables (which are in the workspace too) are not being recognised.
%% Damped Oscillating Spring System
m_c = 2; %Container mass in kg
s1 = 16.0; % Spring constant, spring 1, N/m
s2 = 16.0; % Spring constant, spring 2, N/m
c = 2.0; % Damping Coefficient, Ns/m
d = 0.6; % Initial gap between mass and spring 2, m
t_total = 20.0; % Total interation time, s
dt = 0.01; % Interation Step, s
x =1; % Initial displacement, m
g = -9.81; % Gravitational Acceleration, m/s^-2
t = 0: dt: t_total; % Total Time for plotting graphs
r_m = 0.1; % Rate of mass of fluid change in kg/s
m_f_max = 4; % Maximum Fluid mass
%Then there is a choice menu and other calculations where the cases are all set out:
case {4} %Select if the containter is filled with fluid duing the simulation
[r_m] = fluidcalcs();
function [r_m] = fluidcalcs()
r_m = input('Rate of Change of Fluid Mass (kg/s)?\n\n');
if (r_m * t_total) > 4
disp('Invalid Entry - Maximum Fluid Mass is 4kg\n\n');
r_m = input('Rate of Change of Fluid Mass (kg/s)?\n\n');
end
end
In this case the 't_total' variable is not being recognised. The code works fine if I replace the variable name with the value. But the varables need to be changed each time so having a set value isn't what I want.
Any solutions?

That structure is not valid. case is only valid inside switch() but you cannot define a function inside of switch.

Maybe you should try to look for the function on the 'Add Ons' section so you could find the package which contains the function you need. All you have to do is to install the package.

I am getting 'Unrecognized function or variable 'dicm2nii'' when trying to use dicm2nii . Any suggestions for why this function isn't working?

Hi!
I am getting an error calculating the lyaprosen. The error I get is
"Unrecognized function or variable 'dist'.
Error in lyaprosen (line 106)
Dmm=dist(EEMmm(:,1:k)')"
