MatStructure#
Indicates if two matrices have the same nonzero structure
Synopsis#
Values#
SAME_NONZERO_PATTERN
- the two matrices have identical nonzero patternsDIFFERENT_NONZERO_PATTERN
- the two matrices may have different nonzero patternsSUBSET_NONZERO_PATTERN
- the nonzero pattern of the second matrix is a subset of the nonzero pattern of the first matrixUNKNOWN_NONZERO_PATTERN
- there is no known relationship between the nonzero patterns. In this case the implementations may try to detect a relationship to optimize the operation
