Dear all,
I am interested in doing a small thing (perhaps).
I wish to have an 'indexed function'
The purpose would be to have something like
**************
f = symbols('f', cls=IndexedFunction)
i = Idx('i')
print diff(f[i](x),x)
**************
I cannot compute derivatives if the dependency to x is not provided.
1) Can it be done ?
2) Is this a proper way to asses derivatives of vector/tensor fields and
associated derivatives ?
Thanks in advance for your help.
