What you get with: val = [0.5./n:1./n:(n - 0.5)./n]

What this results in. Thanks in advance

[Walter Roberson]

Is n given? Is it positive? Is it at least 1 ? Is it at least 1/2 ?

Answer 1

[Roger Stafford]

Provided n is a positive integer, you get the following row vector with n elements:

 [1/(2*n),3/(2*n),5/(2*n), ... ,(2*n-1)/(2*n)]

I am not sure this is entirely accurate with regards to the actual implementation. See my question on how COLON works. The COLON function is pretty smart when it comes to minimizing floating point error accumulation.

Indeed:

n = 5 ;
x = [0.5./n:1./n:(n - 0.5)./n]
y = [0.5:1:(n-0.5)]./n
% looks the same, but
isequal(x,y), x-y
