<p>Partial Convolution is equivalent to Convolution except that a subset of the output samples is generated. Each function has two additional arguments. <code>firstIndex</code> specifies the starting index of the subset of output samples. <code>numPoints</code> is the number of output samples to compute. The function computes the output in the range <code>[firstIndex, ..., firstIndex+numPoints-1]</code>. The output array <code>pDst</code> contains <code>numPoints</code> values.</p>
|
||
|
|
<p>The allowable range of output indices is [0 srcALen+srcBLen-2]. If the requested subset does not fall in this range then the functions return ARM_MATH_ARGUMENT_ERROR. Otherwise the functions return ARM_MATH_SUCCESS. </p>
