I am not sure about what i am doing wrong but i keep getting this error. i am honeslty very confused. It would be great if i could get some help on how to fix this.
Error:
Index exceeds the number of array elements (0).
Error in pdepe (line 181)
if m > 0 && xmesh(1) < 0
Error in Project (line 38)
sol = pdepe(m,@pdex1pde,@pdex1ic,@pdex1bc,r,t);

Hi,
Error - "Index exceeds the number of array elements" represents that you are indexing an array with some 'n' number of elements, but you are querying for some i-th element, where i > n.
You can try to find out which indexing operation in line 38 is raising this error by displaying each one of them.
