Hello. I am looking to create a 1xn matrix where I would enter a max value and a step size for the vector where each value alternates sign. For example I would enter a max value of 20 and a step size of 5 and the result would produce the following matrix;
[0 5 -5 10 -10 15 -15 20 -20]
Thank you in advance.

maxV = 20;
stepS = 5;
I = zeros(1,2*(maxV/stepS)+1);
I1 = 0:stepS:maxV;
I2 = -I1(2:end);
I(1:2:end) = I1;
I(2:2:end) = I2;
I
