using solve for 2 equations and 2 unknowns

using solve for 2 equations and 2 unknowns C and D

S=solve(['(x0+(b/a))^2+(y0+(D/a))^2=(C^2/(a)^2)',... '(x1+(b/a))^2+(y1+(D/a))^2=(C^2/(a)^2)'],['C','D']);

ok, and what's your question ?

Sorry,

syms C D S=solve(['(x0+(b/a))^2+(y0+(D/a))^2=(C^2/(a)^2)',... '(x1+(b/a))^2+(y1+(D/a))^2=(C^2/(a)^2)'],['C','D']);

I wanted to solve for C and D in the equations. All the other variables are parameters. They define two points (x0,y0)and (x1,y1) on a curve with radius C^2/a^2 and centre (D/a, b/a) where b and a are known. How do I do it!

[Torsten]

syms C D x0 y0 a b

[solC,solD]=solve([(x0+b/a)^2+(y0+D/a)^2==C^2/a^2,(x1+b/a)^2+(y1+D/a)^2==C^2/a^2],[C,D])

does not work ?

Best wishes
