Due to an increase in demand for and questions about direct disk access for Micrososft platforms, and due to the fact that Microsoft has no API for direct disk access, I am releasing this library much earlier than I intended at that start. I am still working on this code.

多变量预测控制，运用于两输入两输出的情况，显示输入输出。(Multivariable predictive control, applied to the case of two-input two outputs, display input and output.)

多项式和非多项式曲线拟合，多项式拟合在matlab中可以使用polyfit函数求解多项式系数，通过polyval函数求解拟合多项式在某数据点处的值(Polynomial and non-polynomial curve fitting, polynomial fitting in matlab polyfit function can be used to solve polynomial coefficients, solve the value of a data point to fit a polynomial function by polyval)
