Finds the relative maxima and minima of functions of several variables in a given interval. You control the maximum error in the computations. Intervals may be explored in search of multiple solutions. Finds the relative maxima and minima of multivariable functions in a given interval. It can fully explore defined intervals to search for multiple solutions or quickly find solutions starting with random seeds. You may predefine constants and specify the error bound for the results. Handles a wide variety of functions, including trigonometric and hyperbolic functions. Results can be saved or printed. Includes a help file with instructions, example and methodology.
