For pdetool GUI, the relevant documentation is here: http://www.mathworks.com/help/pde/ug/coefficients-for-scalar-pdes-in-pdetool.html
From a MATLAB script, the documentation is here:
Matrix coefficient in PDE toolbox for an elliptic equation

When using the PDE toolbox to solve an elliptic equation
- div ( c * grad(u) ) = f
can c be a matrix that is a function of x and y (s.p.d., uniformly elliptic)? Or only scalar valued? If so, can anyone provide the proper syntax or appropriate reference in the documentation? Many thanks!
