Legendre Transform

[Timothy Stitt]

Hi all,

I am not sure if this query is directly related to the PETSc library per 
se, but I was wondering if anyone knows of an efficient implementation 
of the Legendre Transform. A parallel implementation would be even more 
ideal.
I don't know that much about the implementation of integral 
transforms...could it be done in PETSc for instance, if no suitable 
library exists? A web search doesn't throw up to many relevant hits.

Thanks in advance for any guidance given,

Best,

Tim.
