Grapher and matrices

**Grapher.app (MacOS X/Applications/ Utilities) is able to compute with matrices of dimensions up to 3x3. Tests with real or complex matrices, constant or variable, and numerical tests allowed me to check the validity of the calculations and the relevance of the final matrix that results.
But this final matrix does not display its elements if they are variable, and if they are constant numerical values ​​are readable but cannot be selected for transfer by “copy and paste" in equations. Extract the elements of a variable matrix is essential to plot, for example, response curves of interconnected quadripoles (two-port networks) and other useful graphs and parametrers.
If someone finds a simple manoeuvre that lets you select and copy each element of the matrix result, please let me know.

Thanks for being helpful,
