MATLAB: System implementation for loop

Question

Hi, how can I set up this kind of system? My X vector has 84 elements, I want to implement this system :

z1 = 100 + X(1);

z2 = z1 + X(2);

z3 = z2 + X(3);

z4 = z3 + X(4);

etc…for 84 elemens

thanks in advance

Answer 1

Don't create a list of 84 distinct numbered variables. This is a bad idea, terribly poor programming style. It willl create buggy code, and slow code if you try to use those variables.

However, it is trivial to create a new vector with that property.

z = cumsum(X);
z(1) = z(1) + 100;
