2.3.10. VectorPower
Description
VectorPowercomputes the power of a source vector as the sum of the squares of its elements.
Prototype
fractional VectorPower(int numElems, fractional* srcV);
Arguments
Parameters 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 ofsum-of-squaresis larger than the maximum value of 1.31 fractional data type,
the operation results in saturation.
