多項式の読み込み (Scilab ゲートウェイ)

リスト中に多項式の行列を読み込む方法.

呼び出し手順

入力引数プロファイル:

SciErr getMatrixOfPolyInList(void* _pvCtx, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbCoef, double** _pdblReal)
SciErr getComplexMatrixOfPolyInList(void* _pvCtx, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbCoef, double** _pdblReal, double** _pdblImg)

名前指定変数プロファイル:

SciErr readMatrixOfPolyInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbCoef, double** _pdblReal)
SciErr readComplexMatrixOfPolyInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbCoef, double** _pdblReal, double** _pdblImg)

引数

_pvCtx

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

_piParent

新規要素の親のアドレス.

_pstName

"名前指定" 関数の変数名.

_iItemPos

リストにおける新規要素の位置.

_piRows

返される変数の行数.

_piCols

返される変数の列数.

_piNbCoef

返される各多項式の係数の数. (メモリ確保が必要)

_pdblReal

係数の実部を保持する double* 配列のアドレス. (大きさ: _iCols * _iRows, メモリ確保が必要)

_pdblImg

係数の虚部を保持する double* 配列のアドレス. (大きさ: _iCols * _iRows, メモリ確保が必要)

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の行列を読み込む方法を説明します.
