                             NoDataException

Create a new FieldMatrix<T> using the input array as the underlying data array.

The input array is copied, not referenced. This constructor has the same effect as calling Array2DRowFieldMatrix(FieldElement[][], boolean) with the second argument set to true.

                             NoDataException

Create a new FieldMatrix<T> using the input array as the underlying data array.

The input array is copied, not referenced. This constructor has the same effect as calling Array2DRowFieldMatrix(FieldElement[][], boolean) with the second argument set to true.

Parameters:

Parameters:

d - Data for the new matrix.

copyArray - Whether to copy or reference the input array.

Throws:

DimensionMismatchException - if d is not rectangular.

NoDataException - if there are not at least one row and one column.

walkInColumnOrder

public T walkInColumnOrder(FieldMatrixChangingVisitor<T> visitor,
                           int startRow,
                           int endRow,
                           int startColumn,

                    throws OutOfRangeException,
                           NumberIsTooSmallException

Visit (and possibly change) some matrix entries in column order.

Column order starts at upper left and iterating through all elements of a column from top to bottom before going to the topmost element of the next column.

Specified by:

walkInColumnOrder in interface FieldMatrix<T extends FieldElement<T>>

Overrides:

walkInColumnOrder in class AbstractFieldMatrix<T extends FieldElement<T>>

Parameters:

visitor - visitor used to process all matrix entries

startRow - Initial row index

endRow - Final row index (inclusive)

startColumn - Initial column index

endColumn - Final column index

Returns:

the value returned by FieldMatrixChangingVisitor.end() at the end of the walk

Throws:

OutOfRangeException - if the indices are not valid.

NumberIsTooSmallException - if endRow < startRow or endColumn < startColumn.

startColumn - Initial column index

endColumn - Final column index

Returns:

the value returned by FieldMatrixPreservingVisitor.end() at the end of the walk

Throws:
