MatIJGetMinRowSize
returns the largest number of nonzero columns in all of this processor's rows nonzero rows, or zero if no local nonzero rows exist. If MatIJ (equivalently, the underlying graph) is regarded as a multivalued mapping on integers, then the result is the size of the smallest nonempty set among the images of this processor's indices. If all images are empty, the result is zero. Not collective.
