cosspace

Utility function operates with no loops, so is of comparable speed to LINSPACE.

Using the same syntax as LINSPACE, COSSPACE makes a cosine spaced vector, clustering the elements toward the endpoints with greater spacing in the middle:
||_|__|___|____|_____|_____|____|___|__|_||

Given negative vector length, COSSPACE returns an inverse cosine spaced vector with elements sparse toward the endpoints:
|_____|____|___|__|_|_|_|_|_|__|___|____|_____|

An optional input in addition to the endpoints and the number of elements lets you choose the intensity of the clustering.
