SYNOPSIS

SUBROUTINE RELSD(X,N,Iwrite,Xrelsd)

DESCRIPTION

RELSD(3f) computes the sample relative standard deviation of the data in the input vector X.

The sample relative standard deviation = (the sample standard deviation)/(the sample mean).

The denominator N-1 is used in computing the sample standard deviation.

The sample relative standard deviation is alternatively referred to as the sample coefficient of variation.
