Field Detail

rowIndexes

public int[] rowIndexes

rowIndexes holds an integer array of row indexes of all the quadratic terms. A negative integer corresponds to an objective row, e.g. -1 for 1st objective and -2 for 2nd.

varOneIndexes

public int[] varOneIndexes

varOneIndexes holds an integer array of the first varialbe indexes of all the quadratic terms.

varTwoIndexes

public int[] varTwoIndexes

varTwoIndexes holds an integer array of the second varialbe indexes of all the quadratic terms.

coefficients

public double[] coefficients

coefficients holds a double array all the quadratic term coefficients.

Constructor Detail

QuadraticTerms

public QuadraticTerms()

Default constructor.
