hi maxio
you can use diag package.
(%i1) load("diag.mac");
Warning - you are redefining the MACSYMA function EIGENVALUES
Warning - you are redefining the MACSYMA function EIGENVECTORS
(%o1) diag.mac
(%i2) a:Matrix([b,c],[0,d])$
(%i3) mat_function(exp,a);
[ d b ]
[ b c %E %E c ]
[ %E ----- - ----- ]
(%o3) [ d - b d - b ]
[ ]
[ d ]
[ 0 %E ]
