sinspace

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

Using the same syntax as LINSPACE, SINSPACE makes a sine-spaced vector, clustering the elements toward the endpoint:
|_____|_____|____|___|__|_||

Given negative vector length, SINSPACE clusters points toward the beginning rather than the end of the vector.

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