Summary
Convert a SCIRun Matrix to a single Nrrd in the case of a Dense or Column Matrix or convert a Sparse Row Matrix to three Nrrds (Data, Rows, and Columns).
Detailed Description
Convert a SCIRun Matrix to a single Nrrd in the case of a Dense or Column Matrix or convert a Sparse Row Matrix to three Nrrds (Data, Rows, and Columns).
If the input Matrix is a Column Matrix, the module will produe a 1D Nrrd of doubles containing the data.
If the input Matrix is a Dense matrix, the module will produce a 2D Nrrd of Doubles.
If the input Matrix is a Sparse Row Matrix, the module will produce three Nrrds. The first output port contains the Data as a 1D Nrrd representing the non-zero entries in the Sparse Row Matrix. The second output will contain the Rows Nrrd which is the row accumulation buffer containing R+1 entries where R is the number of rows and Rows[N+1]-Rows[N] is the number of non-zero entries in row N. The last output will be the Columns Nrrd containing the column number for each non-zero data entry.
