x

madness object.

type

character string, specifying the type of matrix norm to be computed. A character indicating the type of norm desired.

"O", "o" or "1": specifies the one norm, (maximum absolute column sum);
"I" or "i": specifies the infinity norm (maximum absolute row sum);
"F" or "f": specifies the Frobenius norm (the Euclidean norm of x treated as if it were a vector);
"M" or "m": specifies the maximum modulus of all the elements in x; and
"2": specifies the “spectral” or 2-norm, which is the largest singular value (svd) of x.
