umRow [Action][Matrix][Row&Column][mRow]

Function: Multiplies the elements of a specific row in a matrix by a specific expression.

Syntax: mRow (Exp, Mat, row number [ ) ]

Example: To multiply row 1 of the matrix [[1, 2] [3, 4]] by x

umRowAdd [Action][Matrix][Row&Column][mRowAdd]

Function: Multiplies the elements of a specific row in a matrix by a specific expression, and then adds the result to another row.

Syntax: mRowAdd (Exp, Mat, row number-1, row number-2 [ ) ]

Example: To multiply row 1 of the matrix [[1, 2] [3, 4]] by x, and then add the result to row 2

urowAdd [Action][Matrix][Row&Column][rowAdd]

Function: Adds a specific matrix row to another row.

Syntax: rowAdd (Mat, row number-1, row number-2 [ ) ]

Example: To add row 1 of the matrix [[1, 2] [3, 4]] to row 2

urowDim [Action][Matrix][Row&Column][rowDim]

Function: Returns the number in rows in a matrix.
