I'm looking for at function that is equivalent to Maple's match function:
The match function returns true, because the LHS and the RHS of the equation can be matched for all s. The return variable m contains the values of the unknowns, A and B, that solve the equation for all s.
Does MATLAB offer a function similar to Maple's match function?

syms s ;
A = 1; B = -1;
LHS = 1/s-1/(s+1) ;
RHS = A/s+B/(s+1) ;
m = isequal(LHS,RHS) ;

Okay,...it is like partial fractions?

Well, for the example above I could apply partial fractions. However, I would like to be able to match expressions in more general terms. Here is another example where I want to find a particular solution for a differential equation by using the method of undetermined coefficients.
