How to create a matrix to contain possible combinations of 2 sets of 1D parameters

Question

0 个投票

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!

If you mean all possible permutations, do this:

x = 0:.5:2;
I = npermutek(x,2)  
I =
           0         0
           0    0.5000
           0    1.0000
           0    1.5000
