textmatrix Extension

This simple extension treats the text of the active text editor document as a matrix (where elements are separated by whitespace) and offers some simple matrix operations.

To apply an operation, open the command palette in vscode (F1 or ctrl-shift-p) and search for one of the commands described below (or search for textmatrix to find all commands). The commands are also availble in the context menu of the editor that is accessible by right clicking in the editor.

Be aware that the text in the currently active editor window (representing a matrix), is replaced with the result of the matrix operation.

The text must represent a rectangular matrix with the exact same amout of elements on each line, separated by whitespace. A simple, valid matrix e.g. is:

1 2 3
4 5 6

or

1    2 3    4
  5 6 7   8

The resulting matrix of the operation is always printed out with one space between every element.
