# compactMatrixForm -- global flag for compact printing

## Synopsis

• Usage:
compactMatrixForm = x
• Consequences:
• changes the display of matrices

## Description

compactMatrixForm is a global flag that specifies whether to display matrices in compact form.

The default value is true. The compact form is the form used by Macaulay, in which the multiplication and exponentiation operators are suppressed from the notation.

 i1 : R = ZZ[x,y]; i2 : f = random(R^{2},R^2) o2 = {-2} | 8x2+xy+3y2 7x2+8xy+3y2 | 1 2 o2 : Matrix R <--- R i3 : compactMatrixForm = false; i4 : f | 2 2 2 2 | o4 = {-2} | 8x + x*y + 3y 7x + 8x*y + 3y | 1 2 o4 : Matrix R <--- R
