Method Detail

checkSize

public void checkSize(AbstractMatrix1D B)

Sanity check for operations requiring two matrices with the same size.

Throws:

java.lang.IllegalArgumentException - if size() != B.size().

index

public long index(int rank)

Returns the position of the element with the given relative rank within the (virtual or non-virtual) internal 1-dimensional array. You may want to override this method for performance.

Parameters:

rank - the rank of the element.

size

public long size()

Returns the number of cells.

Specified by:

size in class AbstractMatrix

stride

public int stride()

Returns the stride.

toStringShort

public java.lang.String toStringShort()

Returns a string representation of the receiver's shape.
