I have a vector, and I want to calculate the sum of the values at each step. For example, A = [18;15;125;48;78;69;48;15;12;2]. I want to calculate the sum of the values in a vector. I mean, I want C = [18;18+15;18+15+125;18+15+125+48;...]. How can I do that?

Ran in:
A = [18;15;125;48;78;69;48;15;12;2];
s = cumsum(A)
s = 10×1
18 33 158 206 284 353 401 416 428 430
