多項式の書き込み (Scilab ゲートウェイ)

リスト中に多項式の行列を追加する方法.

呼び出し手順

入力引数プロファイル:

SciErr createMatrixOfPolyInList(void* _pvCtx, int _iVar, int* _piParent, int _iItemPos, char* _pstVarName, int _iRows, int _iCols, const int* _piNbCoef, const double* const* _pdblReal)
SciErr createComplexMatrixOfPolyInList(void* _pvCtx, int _iVar, int* _piParent, int _iItemPos, char* _pstVarName, int _iRows, int _iCols, const int* _piNbCoef, const double* const* _pdblReal, const double* const* _pdblImg)

名前指定変数プロファイル:

SciErr createMatrixOfPolyInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, char* _pstVarName, int _iRows, int _iCols, const int* _piNbCoef, const double* const* _pdblReal)
SciErr createComplexMatrixOfPolyInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, char* _pstVarName, int _iRows, int _iCols, const int* _piNbCoef, const double* const* _pdblReal, const double* const* _pdblImg)

引数

Scilab環境ポインタ, api_scilab.hで定義された"pvApiCtx"で指定.

_iVar

代入する変数のScilabメモリ上の位置.

_pstName

"名前指定" 関数の変数名.

_piParent

新規要素の親のアドレス.

_iItemPos

リストにおける新規要素の位置.

_pstVarName

多項式の変数名 (Scilab5: 最大4文字).

_iRows

新規変数の行数.

_iCols

新規変数の列数.

_piNbCoef

各多項式の係数の数.

_pdblReal

係数の実部を保持する double* 配列のアドレス. (大きさ: _iCols * _iRows)

_pdblImg

係数の虚部を保持する double* 配列のアドレス. (大きさ: _iCols * _iRows)

SciErr

エラーメッセージの履歴と最初のエラー番号が保存されるエラー構造体.

説明

このヘルプはリスト中に多項式を追加する方法を説明します.
