Matrix Calculator

Simple and usable in the terminal/command line.
Build a matrix of any size row by row.

More features will be added in the future.

Easy start

Make sure you have at least Python 3.10 installed on your computer with pip.

$ pip install MatrixCalcs

Furthermore, use the terminal/commandline to start the app:

$ matcalc

The following should appear:

Use <help> command to have more information.
Matrix Calc > [Command]

Use 'create' command to create your first and main matrix.

Matrix Creation

Matrix Calc > create

This should appear:

==========================================================
Please enter your matrix row by row.
Make sure each row has the same number of elements.
Follow the following formats:
Format 1:
	Enter row: 1, 2, 3, 4
Format 2:
	Enter row: 1 2 3 4
	
When done, input 'done' or press Enter key. (Not case sensitive)
==========================================================

Just enter one row after the other following the formats above and input done when you are finished building your matrix.

Documentation

The calculator can hold up to two different matrices at the same time, your main matrix and the 'other' matrix. The main matrix is always on the left side of the equation.

Single matrix

With your matrix, you have multiple possibilities:

Code	Effect
create	Create your main matrix.
det	Gives the determinant of your matrix if possible
trans	Gives the transpose of your matrix
invert	Gives the invert of your matrix if possible
add	Gives the possibility to add another matrix
show [flag]	Show matrix -m (main)
use	Use operation result and store it
clear	Clears the window.
restart	Restart with a new matrix
help	Gives the list of commands
exit	Exit the application

Two matrices

After adding another matrix, using 'add' mentioned above, you have other possibilities:

Code	Effect
back	Go back to your first matrix only
madd	Matrix addition if possible
sub	Matrix subtraction if possible
dot	Dot product if possible
cross	Cross product if possible
switch	Switches order of the main and 'other' matrix
show [flag]	Show matrix -m (main) -o (other) -b (both)
use	Use operation result and store it
clear	Clears the window.
help	Gives the list of commands
restart	Restart with a new matrix (both)
exit	Exit the application

Command 'use'

The use command needs two options, the operation and where to store it.

Matrix Calc > use [operation] [location]

The possible operations are:

• transpose (trans)
• inversion (invert)
• addition (madd)
• subtraction (sub)
• dot product (dot)
• cross product (cross)

The possible locations are:

• Main matrix (m or -m)
• Other matrix (o or -o)
