Description

It would be handy in differential equations to be able to do differentiation and integration of matrices and vectors, with the exact same answer as obtained by using the apply_map method.

  • summary changed from derivative and integral of a matrix to derivative of a vector and a matrix.

This depends on #4713

I guess the integral of a matrix doesn't come up that often, so I'm changing my request. Besides, the integral can calculated using the apply_map function at #4713 for vectors or the existing apply_map function for matrices.
