Jacobian
2D/3D

Jacobian[cnum, bnum] returns the submatrix of the current Jacobian associated with constraint cnum and body bnum.
• The cnum argument can take any of the forms accepted by
Constraints to obtain Jacobian terms from multiple constraints.
• The bnum argument can take any of the forms accepted by Loads to obtain Jacobian terms from multiple bodies.

Jacobian[All, All] returns the entire Jacobian matrix.
• See also:
Constraint.

Further Examples

Load the Modeler2D package and define a simple model.

Here are the entire rows of the Jacobian matrix associated with the Translate2 constraint.

Here are the rows associated with multiple constraints and columns associated with multiple bodies.
