Thank you both very much. I have found a solution myself but with more 'hassle' around it then yours. f[s_] := (s^2 + 3) / ((s - 1)^2 (s + 1)) == A1 / (s - 1) + A2 / (s - 1)^2 + A3 /( s + 1) Solve[ { f[s] /. s -> 0, f[s] /. s -> 2, f[s] /....
Thank you very much, this works fine! Chiel Geeraert
I found it : forgot a semicolon in the code While[i
Really a nice solution. I learned quite a few things from all reactions. Best regards, Chiel Geeraert (Netherlands)
