linspace_round

Creates linearly spaced vector with "rounded" intervals.

LINSPACE_ROUND generates a row vector of equally spaced points that bound the input values. The spacing is chosen such that tenths and quarters are considered "rounded" fractions.

Example: If X1 = 3.4, X2 = 7.5, N = 6,
then LINSPACE_ROUND(X1,X2,N) returns:
[2.8 3.5 4.2 4.9 5.6 6.3 7.0 7.7]
(in words, choosing spacing of 0.7 will produce about 6 points that bound X1 and X2)

This is useful in having automatically chosen data bins, contour intervals, graph tick marks, etc., that are pleasing to the eye.
