update integral to call quadgk for 'ArrayValued' integrations (bug #62468)
* integral.m: Modify integrator selection so that calls with ‘ArrayValued’ go
to quadgk instead of quadv. Remove error checks for previously incompatible
parameter combinations. Update docstring to remove mention of quadv, point
'ArrayValued' reference to quadgk, change returned error parameter description
to match current behavior, and remove parameter incompatibility note. Add BIST
to verify combined parameter functionality, and change BISTs checking quadv
err parameter.
* quadgk.m: Correct parameter name in docstring.
* NEWS.8.md: Under General Improvements add note about quadgk now accepting
'ArrayValued' parameter and update integral improvement description of
optional returned error parameter. Under Matlab Compatibility add note about
integral now accepting all parameter combinations.
