Allow sub2ind() to accept indices outside the size of the input subscripts (bug #62184) * NEWS.8.md: Announce change in Matlab Compatibility section. * sub2ind.cc: Add '#include "utility"' for access to std::swap. * sub2ind.cc (Fsub2ind): Check nargout to figure out ndims of output. For special case of vector (1-dimension), put in code to guarantee a row vector output. Add BIST tests for bug #62184. Remove input validation BIST which no longer applies. * Array-util.cc (ind2sub): Remove input validation requiring index to be within range of subscript size. Adjust code to put all remaining elements in the final output dimension.
