Constructor Detail

DefaultIntMatrix

public DefaultIntMatrix(int rowCount,
                        int colCount)

DefaultIntMatrix

public DefaultIntMatrix(int[] values,
                        int rowCount,
                        int columnCount)

DefaultIntMatrix

public DefaultIntMatrix(int[][] values,
                        boolean rowsInDim1)

Initializes the matrix from a 2-dim int 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 int 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.

DefaultIntMatrix

public DefaultIntMatrix(Integer[][] values,
                        boolean rowsInDim1)

Initializes the matrix from a 2-dim int 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 int 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.
