Function ABS

Function ABS calculates what is known as the Frobenius norm of a matrix. For a

matrix A = [a

]

m×n

, the Frobenius norm of the matrix is defined as

If the matrix under consideration in a row vector or a column vector, then the

Frobenius norm , ||A||

, is simply the vector’s magnitude. Function ABS is

accessible directly in the keyboard as „Ê.

Try the following exercises in ALG mode (using the matrices stored earlier for

matrix operations):

Function SNRM

Function SNRM calculates the Spectral NoRM of a matrix, which is defined as

the matrix’s largest singular value, also known as the Euclidean norm of the

matrix. For example,
