Hello My question is very simple How can pass many big matrices into function. for example my function is:
f=[B(:);C(:);D(:);E(:);G(;)]
B, C, D, E and G are (1045*942) matrices. I can't write again them in function. I created these matrices before and I want to pass them into function only by name.
How can I do it?

function outputs=yourfunction(B,C,D,E,G)
% do whatever to compute outputs with the input arrays
Matlab syntax doesn't care about size or even types of arguments; just refer to them as the variable names and all the rest takes care of itself.
See
doc function
for more details on writing functions in Matlab

Sorry, you're not providing anything near enough information to tell what went wrong. Show the complete code and the code you ran as you ran it, precisely.
If you have a function in an m-file that consists of
function[f]= ave2(B,C)
f=[B(:);C(:)]
end
Then you call it just like any other Matlab function as (in the calling script or at the command line) --
x=rand(3);
y=rand(5);
z=ave2(x,y);
In this case you would get a returned vector z of length 34 (9+25). Inside the function B would be equated to x and C to y.

You could have just tried. But don't worry about it - they're not very big. Even 5 of them is not very big at all.
