makeGaussianMatrix

 

 

Description

The makeGaussianMatrix function returns the M by M+1 system of linear equations representing the coefficient derivative equations for the minimizing the least squares error.

The input argument {NumMatrix} must be an N by M+1 number matrix representing the original independent variable observations with the dependent variable in the last column in the form of:

x x x x... y

x x x x... y

....

x x x x... y

The output argument will be an M by M+1 number matrix containing the dot products of the column vectors of the original observation matrix XY, where: G[r,c] = vectorDotProduct(colXY[r],colXY[c]).

When to use

The makeGaussianMatrix function is a non-destructive function useful when you want to create a Gaussian matrix in preparation for primal form regression. See Sedgewick[2] chap 38.
