JmatrixLMA R Documentation
Calculate a Jacobian Matrix
Description
Calculate the Jacobian matrix with the original dataset and the
current version of fitted data. This is not intended for
external use. It is called from fitConic
Usage
JmatrixLMA(XY, parA, XYproj)
Arguments
XY
The original input dataset
parA
The current set of ABCDEF quadratic equation coefficients.
XYproj
The current calculated dataset based on the latest iteration
of the coefficient set.
Value
Res
residuals based on the norm of XY - XYproj
J
matrix of values for each input data point corresponding
to the terms in the general quadratic Ax^2 + Bxy + Cy^2 +Dx + Ey +F
