I have a for loop inside which, various operations are running. There are a few variable inside that loop which I want to update after every 4 iterations of the loop.
Lets say we have this situation
a = 1:100
Y = 123;
I want this Y to update after 4 iterations as in, for a=1:4, the value of Y remains same and for a=5:8, it remains same and so on.
How should I perform this.
