Method Detail

checkShape

public void checkShape(AbstractMatrix2D B)
Sanity check for operations requiring two matrices with the same number of columns and rows.

Throws:
IllegalArgumentException - if columns() != B.columns() || rows() != B.rows().

checkShape

public void checkShape(AbstractMatrix2D B,
                       AbstractMatrix2D C)
Sanity check for operations requiring matrices with the same number of columns and rows.

Throws:
IllegalArgumentException - if columns() != B.columns() || rows() != B.rows() || columns() != C.columns() || rows() != C.rows() .

columns

public int columns()
Returns the number of columns.


columnStride

public int columnStride()
Returns the column stride.


index

public long index(int row,
                  int column)
Returns the position of the given coordinate within the (virtual or non-virtual) internal 1-dimensional array.

Parameters:
row - the index of the row-coordinate.
column - the index of the column-coordinate.

rows

public int rows()
Returns the number of rows.


rowStride

public int rowStride()
Returns the row stride.


size

public int size()
Returns the number of cells which is rows()*columns().

Specified by:
size in class AbstractMatrix

toStringShort

public String toStringShort()
Returns a string representation of the receiver's shape.
