## Member Function Documentation

void IMpmsm::dfdx_cond | ( | const vec & | x0,
|  | const vec & | u0,
|  | mat & | A,
|  | bool | full = `true` |
| ) |  |  | `[inline, virtual]`

Evaluates and writes result into `A` .

Parameters:

  | full | denotes that even unchanged entries are to be rewritten. When, false only the changed elements are computed.
  | x0 | numeric value of $x$,
  | u0 | numeric value of $u$
  | A | a place where the result will be stored.

Reimplemented from diffbifn.

Parameters:

  | full | denotes that even unchanged entries are to be rewritten. When, false only the changed elements are computed.
