Description
The
histogram
contains samples, and stores the result in the output vector
n
The minimum and maximum value of any input sample is specified by
and , respectively. These values are used by the function to calcu-
min max
late the size of each bin as
output vector
c
Any input value that is outside the range
boundaries of the output vector and will be discarded.
