General/Array is Object to express array. It can express general array (multiple dimension array).
Contents
constant
ARRAY_MAX_DIMENSION: 5 (Maximum dimension of array) ARRAY_MIN_DIMENSION: 1 (Minimum dimension of array)
ARRAY_SEPARATOR " \t\n," (Separator of array)
struct
typedef unsigned long arrayParaTypeInteger;
typedef float arrayParaTypeReal;
typedef struct Array {
arrayParaTypeInteger dim;
arrayParaTypeInteger n[ARRAY_MAX_DIMENSION];
arrayParaTypeReal* A;
} Array;
dim: dimension of array (2D: Matrix, 1D: Vector.) n: Number of elements at each dimension A: Linear vector which stores elements
API
Initialize
extern void arrayInit(Array* a, char* message);
Free
extern void arrayFree(Array* a, char* message);
Output format details
extern void arrayFormatInfoPrint(FILE* fpt, int mode);
File Read
extern void arrayReadFromFile(FILE* fpt, Array* a, char* message);
File Write
extern void arrayWriteToFile(FILE* fpt, Array* a, char* message);
Principal Component Analysis
extern void arrayPCA(Array* u, Array* C, Array* lambda, Array* X, Array* ave, int mode);
| Input | Description |
|---|---|
| X | Coordinates information in Contour level(number of components * number of elements) |
| Output | Description |
|---|---|
| u | Eigenvector of coordinates information(number of components * number of components) |
| C | Covariance of coordinates information(number of components * number of components) |
| lambda | Eigenvalue of coordinates information(number of components) |
| ave | Average coordinates of each component(number of components) |
Get and Set array element
Get or set value of each element by the following function. Caution that type is not automatically converted, since set by #define .
Get
arrayDataGet1(a, i0) arrayDataGet2(a, i0, i1) arrayDataGet3(a, i0, i1, i2) arrayDataGet4(a, i0, i1, i2, i3) arrayDataGet5(a, i0, i1, i2, i3, i4)
Set
arrayDataSet1(a, i0, data) arrayDataSet2(a, i0, i1, data) arrayDataSet3(a, i0, i1, i2, data) arrayDataSet4(a, i0, i1, i2, i3, data) arrayDataSet5(a, i0, i1, i2, i3, i4, data)
