[gradsusr] cdiff

[Muhammad Afzaal]

Hello everybody

I am using "cdiff" function along z-dimension to fine dvar/dz e.g

-> 'set z 1 17'
-> 'define dvar = cdiff(var,z)

but I have following error

Error from CDIFF:  Specified dimension non varying
Operation Error:  Error from cdiff function
  Error ocurred at column 1

can anybody figure out the problem?

Thanks
