Constructor Detail

DefaultLongMatrix

public DefaultLongMatrix(int rowCount,
                         int colCount)

DefaultLongMatrix

public DefaultLongMatrix(long[] values,
                         int rowCount,
                         int columnCount)

DefaultLongMatrix

public DefaultLongMatrix(long[][] values,
                         boolean rowsInDim1)

Initializes the matrix from a 2-dim long array. The resulting rows relate to the first dimension if rowsInDim1 is true, or to the second dimension otherwise. If the second dimension has different lengths, the maximum value is taken, missing values are initialized with 0.

Parameters:

values - The 2-dim long array with the source values

rowsInDim1 - If true, the 1^st dimension will become rows in the resulting DefaultDoubleMatrix, the columns relate to the 2^nd dimension. If false, it is vice versa.

DefaultLongMatrix

public DefaultLongMatrix(Long[][] values,
                         boolean rowsInDim1)

Initializes the matrix from a 2-dim long array. The resulting rows relate to the first dimension if rowsInDim1 is true, or to the second dimension otherwise. If the second dimension has different lengths, the maximum value is taken, missing values are initialized with 0.

Parameters:

values - The 2-dim long array with the source values

rowsInDim1 - If true, the 1^st dimension will become rows in the resulting DefaultDoubleMatrix, the columns relate to the 2^nd dimension. If false, it is vice versa.
