<P>
This command defines <CODE>m1</CODE> to be a matrix
with <CODE>nrow</CODE> rows and <CODE>ncol</CODE> columns, where
<CODE>nrow > 0</CODE> and <CODE>ncol > 0</CODE> must be scalar values.
Other variable names, <CODE>m2 ...</CODE>, may
be included, and they will also be defined to be matrices with the same
number of rows and columns.</P>
<P>
If <CODE>mI</CODE> already is a matrix, it will
either be trimmed down to the specified dimensions or zero filled to expand it.</P>
<P>
If <CODE>mI</CODE> is an existing variable, but not a matrix, it will be destroyed first.</P>
<P>
If <CODE>mI</CODE> does not exist, it will be created and zero filled.</P>
