Mul1D
AnalysisLibErrType Mul1D (double arrayX[], double arrayY[], ssize_t numberOfElements, double outputArray[]);
Purpose
Multiplies two 1D arrays, element by element. Mul1D obtains the ith element of the output array using the following formula:
zi = xi × yi
Mul1D can perform the operation in place; that is, the input and output arrays can be the same.
The following example uses the Mul1D function.
double arrayX[10], arrayY[10], outputArray[10];
AnalysisLibErrType status;
// Generate two arrays of random numbers
status = Uniform (10, 17, arrayX);
status = Uniform (10, 34, arrayY);
status = Mul1D (arrayX, arrayY, 10, outputArray);
Parameters
| Input | ||
| Name | Type | Description |
| arrayX | double [] | The first array used in the array multiplication operation. |
| arrayY | double [] | The second array used in the array multiplication operation. |
| numberOfElements | ssize_t | Number of elements to multiply. |
| Output | ||
| Name | Type | Description |
| outputArray | double [] | The result of the array multiplication. |
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. |
