Financial Toolbox™ provides functions for the mathematical modeling and statistical analysis of financial data. You can perform portfolio optimization taking into account turnover, transaction costs, semi-continuous constraints, and minimum or maximum number of assets. The toolbox enables you to estimate risk, model credit scorecards, analyze yield curves, price fixed-income instruments and European options, and measure investment performance. Time series analysis functions let you perform transformations or regressions with missing data and convert between different trading calendars and day-count conventions.
