Hi all! I'm hoping that someone out there has come across mma packages which have certain special functions built-in. Specifically: The Graetz function (eigenfunction for the ODE R''[r]+R'[r]/r+lambda (1-r^2)R[r]==0, where lambda is an eigenvalue) Certain equations of state for typical thermodynamic cycle working fluids (water, ammonia, etc. . .) The graetz fn I cannot find anywhere. The state equations are available through another mathematics-type program, but with as much time as I have spend learning mma and matlab. I don't really want to go for a third. Can anyone help point me towards any packages which might help (even with commercial packages), or can anyone suggest how I might go about setting something like this up?
