.SH NAME
QccDatasetCalcVectorPowers
\- calculate the power (squared norm) of the vectors of a dataset
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccDatasetCalcVectorPowers(const QccDataset *" dataset ", QccVector " vector_power );
.SH DESCRIPTION
.B QccDatasetCalcVectorPowers()
calculates the squared norm (vector power) of each vector in
.IR dataset -> vectors .
These vector powers are returned as a vector in
.IR vector_power .
.I vector_power
is assumed to be allocated with space sufficient to store the
vector powers; use
.BR QccDatasetGetBlockSize (3)
to find out how many vector-power values will be returned.
.SH "RETURN VALUE"
On success, 0 is returned.  On error, 1 is returned.
.SH "SEE ALSO"
.BR QccDataset (3),
.BR QccVectorNorm (3),
.BR QccDatasetGetBlockSize (3),
.BR QccPack (3)
.SH NOTES
For datasets being accessed via block-based access,
.B QccDatasetCalcVectorPowers()
works on only the current block of the dataset.
