Take the example given here: https://au.mathworks.com/help/pde/ug/eigenvalues-and-eigenfunctions-for-the-l-shaped-membrane.html
The pde coefficients are given as: specifyCoefficients(model,'m',0,'d',1,'c',1,'a',0,'f',0);
However, no matter what I substitute into for 'f' I get the same result.
What's going on?

The 'solvepdeeig' function solves PDE eigen value problems of the form as stated in the documentation here : https://www.mathworks.com/help/pde/ug/pde.pdemodel.specifycoefficients.html
We can see from the form of the equation that 'f' is not a part of the problem. Hence it may be specified as zero.
