Budan-Fourier Test for Non-Negativity of EPT Functions

The Budan-Fourier Technique to Test for Non-Negativity of an EPT Function can be implemented in Matlab by downloading the below m-files. The instruction sheet indicates how the m-files should be saved and also provides examples to demonstrate the Budan-Fourier algorithm in practice. The Zipped File contains the complete folder of m-files or the m-files can be downloaded individually.
