Sparse writing (Scilab gateway)
How to add sparse matrix in a list.
Create from existing data.
Calling Sequence
Input argument profile:
SciErr createSparseMatrixInList(void* _pvCtx, int _iVar, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos, const double* _pdblReal)
SciErr createComplexSparseMatrixInList(void* _pvCtx, int _iVar, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos, const double* _pdblReal, const double* _pdblImg)
Named variable profile:
SciErr createSparseMatrixInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos, const double* _pdblReal)
SciErr createComplexSparseMatrixInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos, const double* _pdblReal, const double* _pdblImg)
Arguments
- _pvCtx
Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.
- _iVar
Position in the Scilab memory where you want to put the variable.
- _pstName
Name of the variable for "named" functions.
- _piParent
Address of the parent of the new item.
- _iItemPos
Position of the new item in the list.
- _iRows
Number of rows of the new variable.
- _iCols
Number of columns of the new variable.
- _iNbItem
Number of non zero itmes in the sparse.
- _piNbItemRow
Number of item in each rows (size: _iRows).
- _piColPos
Column position for each item (size: _iNbItem).
- _pdblReal
Address of real data array (size: _iNbItem).
- _pdblImg
Address of imaginary data array (size: _iNbItem).
- SciErr
Error structure where is stored errors messages history and first error number.
