Matrix as input argument of a matlab function

I want to pass two matrices A and B as input arguments to a function. but I am getting the error "Not enough input argument" I tried a simple function as follows but still I am getting the same error,

 function [ C ] = add( A, B )
%ADD TWO MATRICES A AND B
C=A+B;
end

Are you calling the function from your command window, or are you just hitting "run" in your editor? From the command window, the function works fine for me.

[Bijoy]

At the time of executing the function itself by hitting the "run" in the editor where I wrote the function. I want to call this function in another script.

The "run" button does not define input arguments in the default setup - how could it. So using this function from another script, function or the command window will work with C = add(A, B).

[John]

To call the function from another script you might need to add something like this to the top of that script:

addpath(genpath('C:\whereyourfunctionissaved'));

also it needs to be saved as add.m

Sounds like your problem is that you're using the run button- that doesn't work.

Answer 2

[James Tursa]

How are you calling the function? E.g., are you doing this:

A = rand(2,2); % sample data
B = rand(2,2); % sample data
C = add(A,B);

[Bijoy]

yes

Answer 3

[Roger Stafford]

Check that you don't have another function named 'add' on your system that calls for more than two inputs and is being mistakenly called instead of your current 'add' function.

[Bijoy]

I don't think so.

[Jan]

Thinking is less helpful as asking Matlab for a precise answer:

which add -all
