How to add matrices in a function with varying input arguments

5 views (last 30 days)
I have a function: myfunction(varargin), where the varargin are matrices. I want this function to add all of the matrices I input. Hows the best way of doing this?

Do you mean simply adding up all of the varargin individual inputs, like this?
if( nargin )
matrix_sum = varargin{1};
for k=2:nargin
matrix_sum = matrix_sum + varargin{k};
end
end

You can use one cell array containing all your matrices

M1=[1 2;3 4] % first matrix
M2=[1 2 3;0 1 0]% second matrix
M={M1,M2}
Use M as cell array, where
M{1} %is the first matrix
M{2} % the second matrix

Sorry I dont think I was clear. I want to create a function that no matter how many matrices I input, it will add them together. All of the matrices will have the same dimensions.
So if I had: M1=[1 2 3; 4 5 6] M2=[2 3 4; 5 6 7]
myfunction(M1,M2)
it'll out put
[3 5 7;9 11 13]
