CxOuterProduct
Advanced Analysis Library Only
AnalysisLibErrType CxOuterProduct (NIComplexNumber vectorX[], ssize_t numberOfElementsInX, NIComplexNumber vectorY[], ssize_t numberOfElementsInY, void *outerProduct);
Purpose
Calculates the outer product of the complex 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 | NIComplexNumber [] | First vector used to compute the outer product. The following C typedef statement defines the ComplexNum structure:
typedef struct { double real; double imaginary; } ComplexNum; |
| numberOfElementsInX | ssize_t | The number of elements in vectorX. |
| vectorY | NIComplexNumber [] | Second vector used to compute the outer product. The following C typedef statement defines the ComplexNum structure:
typedef struct { double real; double imaginary; } ComplexNum; |
| numberOfElementsInY | ssize_t | The number of elements in vectorY. |
| Output | ||
| Name | Type | Description |
| outerProduct | void * | Calculated outer product matrix, as an array of ComplexNum.
typedef struct { double real; double imaginary; } ComplexNum; |
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. |
