Free42 with Matrix Exponential

[Akira Yamada]

Hi,

Free42 seems to accept square matrix for the e^x function, but returns wrong results.

For example, make a matrix [2x2 matrix] with {{0,0},{0,0}} and press e^x.
The correct result must be {{1,0},{0,1}}, Free42 returns {{1,1},{1,1}}.
Next example, input {{0, pi},{-pi,0}} and e^x.
The correct result is {{-1,0},{0,-1}}, Free42 gets {{1,e^pi},{e^-pi,1}}.
Next example, input [3x3 matrix] with {{0,0,0},{0,0,0},{0,0,0}} and e^x.
The correct result is {{1,0,0},{0,1,0},{0,0,1}}, Free42 returns {{1,1,1},{1,1,1},{1,1,1}}.

Is this a bug? or am I operating it in a wrong way?

I am using Free42 3.0.8 and DM42 (DMCP 3.22, DM42 3.20, Free42 3.0.5).
