multiplyElements
public void multiplyElements(ArrayAccess arrayAccess, int startRow, int startColumn, int rows, int columns, long length, long totalTransformLength, boolean isInverse, int modulus) throws ApfloatRuntimeException- Specified by:
multiplyElements
in interfaceNTTStepStrategy
- Overrides:
multiplyElements
in classLongNTTStepStrategy
- Throws:
ApfloatRuntimeException
-
transformRows
public void transformRows(ArrayAccess arrayAccess, int length, int count, boolean isInverse, boolean permute, int modulus) throws ApfloatRuntimeExceptionTransform the columns of the data matrix. Note that this method expects the data to be organized in columns, not rows. The argumentslength
andcount
still mean the length of one transform and number of transforms to be done.- Specified by:
transformRows
in interfaceNTTStepStrategy
- Overrides:
transformRows
in classLongNTTStepStrategy
- Parameters:
arrayAccess
- The memory array to split to columns and to transform.length
- Length of one transform (one columns).count
- Number of columns.isInverse
-true
if an inverse transform is performed,false
if a forward transform is performed.permute
- If permutation should be done.modulus
- Index of the modulus.- Throws:
ApfloatRuntimeException
