AnalysisLibErrType CxMatrixMul (void *matrixX, void *matrixY, ssize_t numberOfRowsInX, ssize_t colsRowsInXY, ssize_t numberOfColumnsInY, void *outputMatrix);
Purpose
Multiplies two complex matrices. CxMatrixMul uses the following formula to obtain the output matrix.
i = matrix row index
j = matrix column index
k = number of columns/rows in X/Y

Ensure that the matrix sizes are valid for matrix multiplication. You must meet the following size constraints:
- matrixX must be n by k.
- matrixY must be k by m.
- outputMatrix must be n by m.
Parameters
Input | ||
Name | Type | Description |
matrixX | void * | First matrix to multiply. The number of columns in matrixX must match the number of rows in matrixY. This matrix must be an array of ComplexNum. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; |
matrixY | void * | Second matrix to multiply. The number of columns in matrixX must match the number of rows in matrixY. This matrix must be an array of ComplexNum. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; |
numberOfRowsInX | ssize_t | The number of rows in matrixX. |
colsRowsInXY | ssize_t | The number of columns in matrixX, which must equal the number of rows in matrixY. |
numberOfColumnsInY | ssize_t | Number of columns in matrixY. |
Output | ||
Name | Type | Description |
outputMatrix | void * | Result of the matrix multiplication, as an array of ComplexNum. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; |
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. |
