Nearest MATLAB

Question

I want to find the index of the nearest element in x=0:0.1:pi/2 to a given number z=0.65 . I already did this, but I need something better: [C,I]=min(abs(xz)) . I is the index of the nearest element.

Answer 1

[C, I] = min(abs(xz)) - this is what I will do - I can not come up with improvements on this. [~, I] = min(abs(xz)) will allow you not to create an unnecessary C variable if you consider this an improvement.
