Sending comma seperated list of vectors to a variable input function

Hello all,

I have a function F that can take a variable number of vectors as input. I.E. it can take F(1:4) or F(1:4, 1:3) or F(1:4, 1:3, 1:2) ... etc.

I would like to be able to send it a variable number of inputs from a script. That is, sometimes the script will call it with 3 vectors as input, or sometimes 10 vectors, etc.

I've tried to use mat2cell which I think would work, but I am having trouble formatting it properly, perhaps I do not understand the help page for it.

Say I have a vector B

>> B = [1:4; 1:4; 1:4]

B =

       1     2     3     4
       1     2     3     4
       1     2     3     4

And I want to call F(1:4, 1:4, 1:4). How do I do this?

I've tried

X = mat2cell(X, 3, 4)

and called F(X{:}), but this does not provide the desired output.

If you can provide any help I thank you in advanced!

This seems to be a problem of your mat2cell call.

B = [1:4; 1:4; 1:4]
X = mat2cell(B, [1,1,1], 4);

Now X is {1:4, 1:4, 1:4} and this works:

F(X{:})

Aha, so I did misunderstand the mat2cell call. Thank you this works exactly as I want it to.

Look up varargin. It's whole purpose in life is what you're describing.

As far as I understand, Mark's problem does not concern getting the list of inputs inside the function, but providing a list of inputs from the caller.

Jan Simon's has the correct interpretation of my question. Thank you for your help though.
