Hello, I'd like to create new variables in a for loop that are matrices. It wolud be something along the lines of:

for i=1:n

ki=

[a(i) b(i) a(i)*b(i) -a(i)*b(i);.......;etc.]

So it would create variables k1,k2...kn with the first row if k1 being a(1) b(1) etc. Any way to do this? This would really help simplify my code.

Creating new variables dynamically is bad practice. Store them in a cell array or in a struct. For example:

C = cell(n,1);
for i = 1:n
A{i} = [a(i) b(i) a(i)*b(i) -a(i)*b(i);.......;etc.];
end

This article was written for Python, but it also applies to Matlab. Here's another article on the topic.

Thanks, didn't know you could make cell arrays like that. Much better than what I wanted to do!
