This editor is a tool in which you easy can edit and work with matrices.
Things like addtion, substraction and multiplication with matrices is preformed by clicking in the menu.
It's also easy to calculate inverse, transpose, determinant & adjunt.
All matrices inside the editor can be used in the main window as any other variable, and if
they change there they will be automatic updated in the editor.
As an example we can solve the linear equation system
x + 2y + 7z = 1
3y + 2z = 2
4x - y + 5z = 3
The first thing we do is to create the coefficient matrix
When we now have this matrix we calculate the inverse matrix by clicking Calculate -> Inverse
Then we get something like this
Next thing to do is to create the solution matrix
Then go back to the inverse matrix m1
and click Calculate -> Multiply -> m1 *= m2
And this is the answer to the equation system x = 1 + 1/3 y = 44/51 z = -5/17
If you would like to have the answer in an inexact decimal format just type m1 = dec m1
the main window, the matrix inside the editor will be automatic updated.
