- y1a = zeros(1,100); offers no advantage. It adds to the execution time.
- "cube operation" is not affected by "variable declaration"

Brief question: faster to zero before direct computation?

Hello all, quick question,
in the simplest of examples,
x1a = linspace(-1,1,100);
y1a = zeros(1,100);
y1a = x1a.^3;
Is it a clear computational speed and economy advantage to declare y1a first with zeros, or not, in this simple case?
Is the cube operation one that does not require nor benefit from variable declaration?
Cheers

Not just confusing. It was wrong; a "no" was missing. I've edited the comment.
