Description
|
|
|
•
|
This routine is part of the liesymm package and is loaded via with(liesymm) .
|
|
•
|
It computes the exterior derivative of the differential form form with respect to the coordinates defined by setup() .
|
|
•
|
For coordinate x,  is a 1-form, and  .
|
|
•
|
Expressions not involving the coordinates are treated as constants. The coordinate list is given by wedgeset(0).
