When I use the following code as a script it works without any error.
% function [A]=myFun()
syms t real %time
syms w(t)
w=formula(w);
% I use this to convert symFun to sym
% so I can access to "A" matrix elements which uses w
A=[sin(w);cos(w)]; % "A" matrix is now a 2*1 sym instead of a 1*1 symfun
% end
But when I want to use the code inside a function which passes A matrix as an output, and I call the function I get this error:
"w" previously appeared to be
used as a function or command,
conflicting with its use here as
the name of a variable.
A possible cause of this error is
that you forgot to initialize the
variable, or you have initialized
it implicitly using load or eval.

Try using W=formula(w) and referring to W afterwards -- so that you are not overwriting function w with non-function w.
