OuterProduct
Advanced Analysis Library Only
AnalysisLibErrType OuterProduct (double vectorX[], ssize_t numberOfElementsInX, double vectorY[], ssize_t numberOfElementsInY, void *outerProduct);
Purpose
Calculates the outer product of the real input vectors x and y.
Let xi represent the elements of the numberElementsX-element vector x for i = 0, 1, 2, . . ., numberElementsX – 1.
Let yj represent the elements of the numberElementsY-element vector y for j = 0, 1, 2, . . ., numberElementsY – 1.
The outer product of these two vectors is a matrix O of dimensions n-by-m, where the (i, j)th element of O is given by
oi, j = xi × yj
Parameters
| Input | ||
| Name | Type | Description |
| vectorX | double [] | The first vector used in the calculation of the outer product. |
| numberOfElementsInX | ssize_t | The number of elements in vectorX. |
| vectorY | double [] | The second vector used in the calculation of the outer product. |
| numberOfElementsInY | ssize_t | The number of elements in vectorY. |
| Output | ||
| Name | Type | Description |
| outerProduct | void * | Calculated outer product matrix, as an array of doubles. If vectorX is of dimensions m and vectorY is of dimensions n, the size of the matrix containing the outer product is m-by-n. |
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. |
