The present code is a Matlab function that provides calculation of the bimodality ratio (BR) parameter of the bimodal distributed data using the fitted probability density function (PDF). The BR is defined as the ratio of the amplitude of the right to the left peak of the PDF. Clearly, the data under consideration must be bimodal by default in order to calculate the BR. The bimodality of the data can be checked using the bimodalitycoeff function at

A few examples are given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.

The code is based on the theory described in:
