• Method Details

• transformColumns

void transformColumns(DataStorage dataStorage0, DataStorage dataStorage1, DataStorage dataStorage2, long startColumn, long columns, long power2length, long length, boolean isInverse, int modulus) throws ApfloatRuntimeException
Transform the columns of a matrix using a 3-point transform.
Parameters:
`dataStorage0` - The data of the first column.
`dataStorage1` - The data of the second column.
`dataStorage2` - 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`
• getMaxTransformLength
