Matrix Row Operations

I made this simple command line program to help me do my homework faster for my Matrix and Linear Algebra course by performing the arithmetic for elementary row operations. I still have to determine the next steps, the operations are simply done on each entry of the row for me...perfectly

Use

The program will prompt the user to enter information during the READ stage. Entry entries of the matrix and separate by a space. After pressing enter, it will prompt again. Enter the same amount of numbers and continue until all rows have been entered. Press enter without any entry to display the matrix and enter op (operation) mode

Consider the following example matrix output after the READ stage has been completed

[[ 2.  8. -5.  3.]
 [10.  4.  9.  9.]
 [ 3. -1.  0.  2.]]

• To perform a type 1 elementary row operation (swap two rows of the matrix), enter the numbers. Examples: 12 31

• To perform a type 2 elementary row operation (multiply/divide a row by a scalar), enter the row number followed by x or / and the scalar. Examples: 2x3 3x-0.5 1/2

• To perform a type 3 elementary row operation (add a row to another row), enter the row to be added, then ], then the target row. Examples: 1]2 3]5

• To combine type 2 and type 3 operations, enter the type 2 operation, then ], then the target of the type 3 operation. Examples: 1x4]2 2/-2]3 5/-1.5]1

• To negate a row, type - then the row number: Examples: -2

  How I used it

  Mostly to bring matrices to Reduced Row Echelon Form. We practiced plenty!
