Hi,

I'd like to apply a function to all combinations of possible input parameters.

I just have 2 input parameters which are both vectors, so I'd like to create a matrix which effectively 'pairs' up my parameters.

Here's my code:

d=@(x,y) min(abs(x-y),1-abs(x-y));
x = 0:0.01:0.95;
y = 0:0.01:0.95;

Thank you!

N

If you mean all possible permutations, do this:

x = 0:.5:2;
I = npermutek(x,2)  
I =
