\brief Расчет суммы элеметов массива
|
||
|
||
\param[in] x
|
||
Указатель на вещественный вектор `x`. \n
|
||
Размер вектора `[n x 1]`. \n
|
||
\n
|
||
|
||
\param[in] n
|
||
Размер вектора `x`. \n
|
||
\n
|
||
|
||
\param[out] s
|
||
Указатель на переменную суммы элементов массива. \n
|
||
По данному указателю будет записан результат работы функции.
|
||
\n
|
||
|
||
|
||
\return
|
||
`RES_OK` если функция выполнена успешно. \n
|
||
В противном случае \ref ERROR_CODE_GROUP "код ошибки".
|
||
|
||
Пример:
|
||
\code{.cpp}
|
||
double y[5] = {0.0, 1.0, 2.0, 3.0, 4.0};
|
||
double s;
|
||
sum(y, 5, &s);
|
||
printf("s = %6.1f% \n", s);
|
||
\endcode
|
||
\n
|
||
Результат выполнения:
|
||
\verbatim
|
||
s = 10
|
||
\endverbatim
