Description |
|---|---|
|
numElems |
Number of elements in the source vectors |
|
srcV |
Pointer to the source vector |
Returns
Value of the vector’s power (sum of squares).
Remarks
If the absolute value of sum-of-squares is larger than the maximum value of 1.31 fractional data type, the operation results in saturation.
This function can be self-applicable.
