Subtracting the next element on a vector? Basic
显示 更早的评论
If I have a vector with n elements, and want a new vector with the subtraction of the first by the second element, and continues...
For exemple: A = [20, 8, 4, 1] turns into B = [(20-8),(8-4),(4,1)]
I started something with
n = length(A);
for k = 1:n
....
but nothing I tried worked them.
Thanks.

A = [20, 8, 4, 1];
B = -diff(A);
