基于matlab的曲线拟合，一种函数的拟合，完整代码(Based on the MATLAB curve fitting based on MATLAB curve fitting)

A programmable-logic controller (PLC) is a compact computer-based electronic system that uses digital or analog input/output modules to control machines, processes, and other control modules. A PLC is able to receive (input) and transmit (output) various types of electrical and electronic signals and use them to control and monitor practically any kind of mechanical and/or electrical system.
