Hello everyone,
I have a quick question, how can i use the matrix lets say
pos = [1 2; 3 3];
as a guide to change the values of another matrix lets say
val = zeros(3);
avoiding for loops. What i want is something like var(pos(1,end,:)) = "some value"

var(sub2ind(size(var), pos(:,1), pos(:,2))) = newvalue;
