AnalysisLibErrType CxOuterProduct (ComplexNum vectorX[], int numberElementsX, ComplexNum vectorY[], int numberElementsY, void *outerProduct);
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

Name | Type | Description |
vectorX | ComplexNum array | First vector used to compute the outer product. The following C typedef statement defines the ComplexNum structure:
typedef struct { double real; double imaginary; } ComplexNum; |
numberElementsX | integer | Number of elements in vectorX. |
vectorY | ComplexNum array | Second vector used to compute the outer product. The following C typedef statement defines the ComplexNum structure:
typedef struct { double real; double imaginary; } ComplexNum; |
numberElementsY | integer | Number of elements in vectorY. |
