Universal matrix calculator written on C#

It is not production quality and is not ready for any professional and/or unsupervised use. However, it should be generally stable.

• Basic matrix operations such as:
  • Addition
  • Subtraction
  • Multiplication
  • Exponentiation (negative degrees too)
  • Determinant
  • Transpose
  • Rank
  • Inversing
• Creating variables through the command line
• Matrix expressions
• History of commands entered

Windows only :(

Requires .NET Core 3.0 Something like this:

 dotnet build -c Release

If you don't want to build it yourself, you can find some pre-built Windows binaries in Releases

Interaction with this calculator occurs using the command line. It serves to store a matrix into a variable and to enter a matrix expression.

The expression for assigning a variable to a matrix looks like this:

A = 1 2 3 : 4 5 6 : 7 8 9

Where A is the name of the variable and 1 2 3 are strings. Sign : serves as a column separator. There can be any number of spaces between numbers, separator and equals. To change the value of a matrix element, go to the variable tab change the element value and press Enter

The matrix expression can look like this:

(A*B)-(C^T)

The following concepts are used for the calculation:

• Subtraction is a sign -
• Addition is a sign +
• Multiplication is a sign *
• Exponentiation is a sign ^
• You can calculate the inverse matrix either by raising the matrix to the power of "-1" for example like this A^-1, or use the function inv() and pass the matrix variable as an argument
• To calculate the determinant, use the det() function and pass it the matrix variable as an argument
• For transposition, it is enough to raise the matrix to the power of T (the capital letter is important) or use the function trans() for example like this A^T or trans(A)
• To calculate the rank, it is enough to use the function rank()

To delete a variable from memory, go to the tab with it and click on the button. The T variable is reserved and this name cannot be used.
