public class DiagonalDistribution
extends org.apache.commons.math3.distribution.AbstractRealDistribution
```
A diagonal parallel to the line y = -x is defined by the sum of x and y.
We cut through two independent distributions along the diagonal line y = xAndY - x. This distribution is an approximation using ApproximateDensityDistribution and is targeted at numerical analysis.

    Creates an approximation of the distribution along the diagonal y = xAndY - x of a joint probability distribution of P(X,Y) = P(X)P(Y)
    
    Parameters:
    
    distX - a RealDistribution specifying P(X) - a marginal distribution of P(X,Y)
    
    distY - a RealDistribution specifying P(Y) - a marginal distribution of P(X,Y)
    
    xAndY - the constraint that specifies the position of the diagonal line (x+y)
