The STANDARD function standardizes each column of an 
matrix. Each column of the input matrix is standardized to have a mean of zero and unit standard deviation, as shown in the
following example:
use sashelp.class; read all var _NUM_ into X[colname=varNames]; close sashelp.class; stdx = standard( x ); print "Standardized Data", stdx[colname=varnames];
