Are you sure that you want to define "psy" a a symbolic variable and work with "phy" afterwards?

Answer 1

[Azzi Abdelmalek]

In your expression exp(6.53*10^18) is infinite (this number is not handled by Matlab)

[Walter Roberson]

Even if you convert it to its symbolic equivalent, you end up dealing with catastrophic cancellation of values in the range of 10^(10^20)). You aren't going to get much further symbolically.
