I need to take 27 uniformly distributed samples from a cosine fuction over the interval (-pi/2, pi/2).

Any ideas?

 

I need to take 27 uniformly distributed samples from a cosine fuction over the interval (-pi/2, pi/2).

I would start by defining a vector

x=1:27

Then scale and shift this as follows

t=-pi/2+pi*(x-1)/26

then take the cosine

Cs_t=cos(t)

This assumes you want to include the endpoints in the vectors, but you didn't say specifically you had to do that.

 

Alternatively:

cos(linspace(-pi/2, pi/2, 27));

 

Alternatively:

cos(linspace(-pi/2, pi/2, 27));

Very cool ! Thanks.
