It's my first time to use mathematica, and I hope to iterate the following equations.
Ci0=-Ci-1,0 ((i-1+q)p a-p q c)/((i+q) p-p q)
C0j=-C0,j-1 ((q p b-(j-1+p) q d)/((q p-(j+p) q)
Cij=-(Ci-1,j ((i-1+q)p a-(j+p) q c)+Ci,j-1 (((i+q) p b-(j-1+p) q d))/(((i+q) p-(j+p) q)
C10=q (c-a)
C01=p (d-b)
where a,b,c,d are variables, p,q are given numbers and $C^{i}_{j}$ can be seen as polynomials in variables a,b,c,d with index $i$ and $j$. It seems the instruction in mathematica is not specific enough, so I turn to here for help.
