.SH NAME

clarkeinv \- Inverse Clarke transform
.SH SYNOPSIS
.HP
.B loadrt clarkeinv [count=\fIN\fB|names=\fIname1\fB[,\fIname2...\fB]]
.SH DESCRIPTION

The inverse Clarke transform can be used rotate a 
vector quantity and then translate it from Cartesian coordinate
system to a three phase system (three components 120 degrees apart).
