Matrix transformation is divided into row transformation and column transformation, both of which have three cases:

(1) Swap two rows (columns) of the matrix;

(2) Multiply a row (column) of a matrix by a non-zero number ;

(3) Add the multiple of a row (column) of the matrix  to another row (column).

Now let's take an example:

1 ) First enter the matrix in the editing area (please refer to " Enter Matrix " for the matrix input method)

2 ) Highlight the equation vector, then right-click the mouse to open the menu, next select "Matrix Transformation" to get the result. 

3 ) Calculation results
