数据类型

提供KML_SPBLAS库函数的数据类型说明。

基本数据类型

整型数据：

typedef int KML_INT;  /*32位整型数*/
#define MAX_KML_INT 0x7FFFFFFD            /* 32位KML_INT的最大值减2，避免rows+2申请内存时溢出 */

复数数据类型：

单精度复数

typedef struct { 
    float real; 
    float imag; 
} KML_Complex8;

双精度复数

typedef struct { 
    double real; 
    double imag; 
} KML_Complex16;

枚举类型

表1描述了KML_SPBLAS的枚举类型。

表1 枚举类型及定义
枚举类型	说明	定义
kml_sparse_status_t	表示函数执行状态。	typedef enum{ KML_SPARSE_STATUS_SUCCESS = 0, /* the operation was successful / KML_SPARSE_STATUS_NOT_INITIALIZED = 1, / empty handle or matrix arrays / KML_SPARSE_STATUS_ALLOC_FAILED = 2, / internal error: memory allocation failed / KML_SPARSE_STATUS_INVALID_VALUE = 3, / invalid input value / KML_SPARSE_STATUS_EXECUTION_FAILED = 4, / e.g. 0-diagonal element for triangular solver, etc. / KML_SPARSE_STATUS_INTERNAL_ERROR = 5, / internal error / KML_SPARSE_STATUS_NOT_SUPPORTED = 6 / e.g. operation for double precision doesn't support other types */ } kml_sparse_status_t;
