S norm

Function: Returns the Frobenius norm of the matrix.

Syntax: norm (Mat [ ) ]

Example: To determine the norm of the matrix [[1, 2] [4, 5]]

Menu Item: [Action][Matrix-Calculation][norm]

S rank

Function: Finds the rank of matrix.

The rank function computes the rank of a matrix by performing Gaussian
elimination on the rows of the given matrix. The rank of matrix A is the
number of non-zero rows in the resulting matrix.

Syntax: rank (Matrix)

S ref

Function: Returns the row echelon form of a matrix.

Syntax: ref (Mat [ ) ]

Example: To obtain the row echelon form of the matrix [[1, 2, 3] [4, 5, 6]]

Menu Item: [Action][Matrix-Calculation][ref]

S rref

Function: Returns the reduced row echelon form of a matrix.

Syntax: rref (Mat [ ) ]

Example: To obtain the reduced row echelon form of the matrix [[2, –1, 3, 19] [1, 1, –5, –21]

[0, 4, 3, 0]]

Menu Item: [Action]
