Schur; Size; Specnorm; Specrad - HP 39g Master Manual

This gives the final result shown in the matrix
M2 on the right, giving a solution of (1, -2, 3).
The huge advantage of this function is that it
allows for inconsistent matrices which can't be
solved by an inverse matrix.
For example, suppose we use the system of equations below, in which the
third equation is a linear combination of the first two but the constant is not
consistent with this - ie no solution.
+ + =

x y z 5

− = −

2 x y 6

+ =
 3 y 2 z 13
The final line of 0 0 0 1 indicates no solution.
