问题
Say I have a function whose outputs are two reals a and b
[a,b]=function(c)
I'd like to get all the outputs in a vector v. v=function(c) doesn't do what I want, v is 'a' only. Of course here I could do v=[a,b]. But the function in question is ind2sub for a N-D array so it gives n outputs that I'd like to have in a vector directly.
Is there a way to do it? Thanks very much!

You can use a cell array and a comma-separated list like so:
X = cell(N, 1);
[X{:}] = function(C);
The syntax X{:} is in fact expanded to [X{1}, X{2}, ...], which provides a valid sink for your function. As a result, each output variable will be stored in a different cell in X.
If each output variable is a scalar, you can flatten out the cell array into a vector by using yet another comma-separated list expansion:
v = [X{:}];
