In mathematics, '''negacyclic convolution''' is a [[Convolution|convolution]] between two vectors ''a'' and ''b''.
It is also called skew [[Circular convolution|circular convolution]] or wrapped convolution. It results from multiplication of a skew circulant matrix, generated by vector ''a'', with vector ''b''.
