input argument type double

when i using my matlab code, this error appear :

Undefined function 'uneldof' for input arguments of type 'double'.

when i write " which uneldof"

it says "'undeldof' not found. "

how can i fix it.

and my code is widesprerasd that i cant bring that on this paper.

Mili - what is the uneldof function? Is that something that you have written that is being called from your code? If so, please show the function signature and how you are calling it (include the data types of the inputs to this function).

[Mili Kian]

yes, the uneldof have written by me.

let me tell you everything.

at firs i have 2D mesh that incluade tatall point.( that its name is edof) .

but i want some points under topography situation.(i called uneldof).you can see below:

uneldof=eldof(points_below(:,1),:);

and at the other function i used just uneldof points to solve my equation.

if you want i can sent my code to you

please heeeeeelp

Is uneldof a function or a variable?

uneldof=eldof(points_below(:,1),:);

The above code indicates it is a variable.

Please post the full error message (all the red text) so that we know which line is causing the problem. The problem could be that you have set this variable (with the same name as the function) and then try to call the function (which is now a variable). Try changing the variable name to something else (do not give the same name as a function).

[Mili Kian]

eldof and uneldof are variable.

the function of my code are:

1-LK

2-massmat

3-IPCGdyri

4-DOfind

5-dampingmat

and one m.file that name is test.2 gives us inner information and show outer result.

the tottal error are in below:(the red lines)

Undefined function 'uneldof' for input arguments of type 'double'.

Error in IPCGdyri (line 72)

x_e(j)=x(uneldof(i,j+1));

Error in test2 (line 33)

[x,ve,ac,u,n]=IPCGdyri(9,9,1,.3,160e6,3,3,BC1,BC2,f,1e-8,.25,1200,.002,0,0,2200,out);

when i put % before "uneldof=eldof(points_below(:,1),:);"

my code work very well

[Geoff Hayes]

Mili - you will need to show your code for IPCGdyri. Does this file also inlcude the line

uneldof=eldof(points_below(:,1),:);

? How does commenting out this line prevent the error from occurring? How is uneldof used after this line of code? And are you sure that you don't have a function named uneldof?

[Image Analyst]

Make sure you spell things correctly. You don't always, like when you said this:

when i write " which uneldof"

it says "'undeldof' not found. "

The variable is not in scope. You need to pass that variable into your functions somehow. See the FAQ for methods on how to do that: FAQ
