Section 12: Calculating with Matrices 177
The > 7 (row norm) and > 8 (Frobenius norm) functions also
operate as conditional branching instructions in a program. If the X-register
contains a matrix descriptor, these functions calculate the norm in the usual
manner, and program execution continues with the next program line. If the
X-register contains a number, program execution skips the next line. In both
cases, the original contents of the X-register are stored in the LAST X
register. This is useful for testing whether a matrix descriptor is in the X-
register during a program.
