[ Matrix Calculator ] PRO

An extended version of the [ Matrix Calculator ]; built from scratch with a lot of new features and improvements.
Supports common operations (+, -, ×, ÷, exponentiation) and matrix operations (rank, determinant, inverse, transpose, LU decomposition).

Rational numbers and decimals
The app uses fractions as default, but you can select to display decimals. Go to system app - Settings and find [ Matrix Calculator ] PRO and move the slider to activate decimal representation.

Landscape
With the horizontal view we added new operations such as sum, subtract and power of a matrix.

Copy & paste
The app allows you to store in the memory unlimited number of matrices. To copy a matrice make a long press gesture on the desired matrix. To paste it you need to make a long press gesture on the screen before starting a new matrix (e.g. after pressing multiplication)

Large number support with repeating detection
The calculator supports large numbers. Moreover, in the decimal representation we implemented automatic detection of a number whose digits are periodic (1/3 is 0.(3))

Unlimited matrix size
You can create a matrix of any size. If the matrix is bigger than the screen you can move it with your finger. The expression on the screen are totally movable!

Day/night mode
We have prepared two color themes - light - which is set as default and dark for those who prefer darker colors or work during the night. To switch between these two themes rotate your device upside down - the theme will change. You can also choose theme while force touching the icon on the home screen.

Transparent mode
We have noticed that is not comfortable to copy from a book after looking at the device's screen. That is why we prepared Transparent mode. It allows to focus the sight just on one thing - the screen - as the app become transparent. It is now possible to watch the book and screen at the same time. To start Transparent mode tap the button on the upper left corner.

Gesture support
Besides the provided buttons to add a row or column we also made possible to perform this actions - adding a row/column - by swiping a finger across the keyboard down or right. The app supports all 4 directions of swiping, to move backwards simply swipe left or up.
