Description copied from interface: NamedMatrix

Get the number of rows the matrix has

Specified by:

rows in interface NamedMatrix

Specified by:

rows in class AbstractNamedDoubleMatrix

columns

public int columns()

Description copied from interface: NamedMatrix

Get the number of columns the matrix has.

Specified by:

columns in interface NamedMatrix

Specified by:

set in interface NamedMatrix

Specified by:

set in class AbstractNamedDoubleMatrix

set

public void set(int i,
                int j,
                double d)

Specified by:

Parameters:

i - row

j - column

d - value

getRowObj

public java.lang.Object[] getRowObj(int i)

Description copied from interface: NamedMatrix

Get a row in the matrix as a generic Object[]. This exists so NamedMatrices can be used more generically.
