Allocation of resvec and gradvec #27

Closed talassio closed 3 years ago

talassio commented 5 years ago

Request to push up to nlls_solve the allocation and filling of inform%resvec and inform%gradvec, so to avoid dealloc's and alloc's at each iteration.

Rationale: If user chooses to use nlls_iterate instead of nlls_solve then resvec and gradvec are of no much use.

Note @tyronerees: nlls_test stringent test uses these arrays for testing... Is it possible to remove these elements and replace/update the test?
