Procedure from library inout.lib (see inout_lib).

Usage:
pmat(M[,n]); M matrix, n integer

Return:
A string representing M in array format if it fits into pagewidth; if n is given, only the first n characters of each column are shown (n>1 required), where a truncation of a column is indicated by two dots (\'..\')

Example:
 
LIB "inout.lib";
ring r=0,(x,y,z),ls;
ideal i= x,z+3y,x+y,z;
matrix m[3][3]=i^2;
pmat(m);
==> x2,     xz+3xy,     xy+x2,         
==> xz,     z2+6yz+9y2, yz+3y2+xz+3xy, 
==> z2+3yz, y2+2xy+x2,  yz+xz
pmat(m,5);
==> x2,    xz+.., xy+x2, 
==> xz,    z2+.., yz+.., 
==> z2+.., y2+.., yz+xz
