How to calculate the polynomial coefficients of any arbitrary polynomial to fit data

Posted August 1, 2016 at 08:06 by Tobi

Dear all,

if you are interested in the calculation of polynomial coefficients to fit some data, you can check the method of least squares on my homepage. Here I explained everything in detail and also gave an example how to build the matrix A and the solution vector b for the problem we are discussing there. The polynomial that I am using in the example is:

$\ln(\mu) = A + B \ln(T) + C\ln(T)^2 + D \ln(T)^3$

How to build the matrix A and the solution vector...

The Pimple Algorithm (21.08.2017)

In this blog I showed (since 2014) a few things about the pimple algorithm and how things are working in OpenFOAM. However, based on the fact that the explanation of the algorithm is given in my book, I removed the content here. The old revised one is still available at the wiki page. Links can be found below.
