Diffrentiation in version 4.0

Please login with a confirmed email address before reporting spam

Hi Folks,
the diff(u,x) function in V3.5 seems not to be supported in V4. That's strange and I suppose there must be a way to differentiate a defined papramer based on gemetric variables. Can you help?

Hi,

The "diff" and "pdiff" operators changed name to "d" and "pd", respectively, starting from version 3.5a, so

d(u,x)

is now the correct syntax.
