Not enough input argumaents

Hi, I am very new to matlab and I am getting that 'not enough input arguments when typing this.

function [sum]=add(x,y)
w=x+y;
disp(w);
end

Answer 1

It depends on how you call this function, try to call if from the command window :

x = 1;
y = 2;
s = add(x,y);

And then you should get an error, think about how the sum variable is calculated.

https://in.mathworks.com/help/matlab/ref/function.html - I suggest you to read it for better understanding and further usage

x = 5; % example values
y = 2;
Result = Add(x,y)
% simply call it 

function w = Add(x,y) % save the function in a separate file named as Add.m , note the name of the file should be same as the function name
w=x+y;
disp(w); %% redundant
end

Note: Don't name variables which are in-built functions of MATLAB.

Clearly you need to know the basics of MATLAB
