Taking data from matrix and using it in a function
4 views (last 30 days)
Let's denote . I would like to find the maximum value of the function z, if I substitute with -1 or 1. I created a matrix of only -1 and 1 using de2bi function (I got 0's and 1's but substituted 0's with -1's). How can I "connect" the matrix with my function, so that I'll check all possible combinations and get the maximum value?

As far as I understand, you want to change E1, E2, E3 and E4 respectively with combinations of -1 and 1. So the following code does that:
syms z(x,y) E1 E2 E3 E4
A=perms([-1 1 -1 1]);
After this point, you can proceed. If you have further question, we can discuss from here. Hope this gives the idea.
