HIST Histogram.
N = HIST(Y) bins the elements of Y into 10 equally spaced containers
and returns the number of elements in each container. If Y is a
matrix, HIST works down the columns.

N = HIST(Y,M), where M is a scalar, uses M bins.

N = HIST(Y,X), where X is a vector, returns the distribution of Y
among bins with centers specified by X.

[N,X] = HIST(...) also returns the position of the bin centers in X.

HIST(...) without output arguments produces a histogram bar plot of
the results.
