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]]

S
eigVl
Function: Returns a list that contains the eigenvalue(s) of a square matrix.
Syntax: eigVl (Mat [
) ]
Example: To obtain the eigenvalue(s) of the matrix [[3, 4] [1, 3]]
