- The data of the third column.startColumn
- The starting element index in the data storages to transform.columns
- How many columns to transform.power2length
- Length of the column transform.length
- Length of total transform (three times the length of one column).isInverse
-true
if an inverse transform is performed,false
if a forward transform is performed.modulus
- Index of the modulus.- Throws:
ApfloatRuntimeException
