Multiply the inverse of the system matrix by the transpose of the given matrix, and multiply the result with the given matrix J.
- Parameters:
-
result the variable where the result will be added J the matrix J to use
- Returns:
- false if the solver does not support this operation, of it the system matrix is not invertible
