Generate simple plots and Lagrange Polynomials for interpolations of given sets of points.

See https://en.wikipedia.org/wiki/Lagrange_polynomial for reference on what those polynomials are.

Usage

This program receives a .csv file as input, which contains two columns (x and y). Each row represents a point in (x, y). See example_data.csv.

Also, a precision value needs to be passed to the program, so it knows the "resolution" of the interpolation. For example: a precision of 0.1 will generate interpolated points every 0.1 units in the x axis.

Finally, an output name needs to be given. The program will generate two files: [outputname]_LaTeX.txt and [outputname].png. The first file will contain the code to represent the polynomial in a LaTeX document and the second is a plot.

In other words: python3 interpolation.py data.csv precision output_name.
