Class

The brobmat class provides basic Brobdingnagian arithmetic for matrices.

Objects from the Class

Objects can be created by calls of the form new("brobmat", ...), although functions brobmat(), as.brobmat() are more user-friendly.

Slots

x:: Object of class "matrix" that specifes the exponent
positive:: Object of class "logical" that specifies the sign
