IntRiffleArray
Advanced Analysis Library Only
AnalysisLibErrType IntRiffleArray (int inputArray[], ssize_t numberOfElements, int seed, ssize_t index[]);
Purpose
Riffles the input array of integer elements by randomly selecting two elements in inputArray, swapping those elements, and then repeating this process numberOfElements times, where numberOfElements is the size of inputArray.
Example Code
/* The following code riffles the elements in input array x. */
int x[20];
int y[20];
int n = 20, i;
for (i = 0; i < 20; i++)
x[i] = i * 2;
IntRiffleArray(x, n, 3, y);
Parameters
| Input | ||
| Name | Type | Description |
| inputArray | int [] | The input array to riffle. inputArray is overwritten by the riffled array on exit. |
| numberOfElements | ssize_t | Number of elements in inputArray. |
| seed | int | The seed value at which to riffle input array. When seed ≥ 0, IntRiffleArray generates a new random sequence using the seed value you specify. When seed < 0, IntRiffleArray generates the sequence as a continuation of the previously generated noise sequence. |
| Output | ||
| Name | Type | Description |
| index | ssize_t [] | The corresponding index in the input array for each element in the riffled array. |
Return Value
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
