This is a Qt application that uses Qwt to plot polynomial approximations based on a set of data points. It employs the least squares polynomial regression algorithm to estimate polynomial coefficients from data points, leveraging Doolittle's LU decomposition to efficiently solve the underlying system of linear equations.
- Qt 5 or later
- Qwt Plot
Use qmake when relying on system's default environment version.
