The indexes must be provided in (row,column) form. Functions in this package are programmed with care so no overflow of linear index is used with large-size matrix. I try to design an engine of automatic selection algorithms so as to provide a good run time performance across various cases. I'm not sure it's worth the effort, but my experience shows that it is easy to mess with the performance when non-appropriate method is using in sparse manipulation. This package does not warranty for best performance, but it just has a modest pretension to prevent user to use bad algorithm. For a better customize solution, a calibration is required on the specific
computer by running this command: spcalib('auto')
