hello every one
I try to do laplace transformation for this array
M = [exp(x) 1; sin(y) i*z];
i do "laplace(M)" but the answer is not correct
I read the help
"syms a b c d w x y z
M = [exp(x) 1; sin(y) i*z];
vars = [w x; y z];
transVars = [a b; c d];
laplace(M,vars,transVars)" but I get error
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
??? Error using ==> sym.maple at 87
Error, (in laplace) invalid input: laplace expects its 2nd argument, t, to be of type name, but
received array(1 .. 2, 1 .. 2,[(1, 1)=w,(2, 1)=y,(1, 2)=x,(2, 2)=z])
Error in ==> sym.laplace at 79
L = maple('map','laplace',F,t,s);
Error in ==> laplace at 5
laplace(M,vars,transVars)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
please help me
