CS5460的模拟版本驱动，模拟SPI端口对CS5460的操作，包括初始化，读操作，写操作，方便初学者使用。

研究杂波环境下多传感器融合的程序，对了解该方法很有帮助！(Research cluttered environment multi-sensor fusion procedure, the method useful for understanding!)

（1）设计一个“简易计算器”，主要实现判断输入的表达式是否合法将中缀表达式转换成二叉表达式树。后序遍历求出表达式的值。能判断输入的表达式是否合法。 （2）用链式存储存储信息，求值时可以采用递归的思想，对表达式进行后序遍历。 （3）将操作结果保存到外部文件。((1) Design a "simple calculator" to judge whether the input expression is legitimate or not and convert infix expression into binary expression tree. The value of the expression is obtained by post-order traversal. Can judge whether the input expression is legitimate. (2) Store information in chain mode. When evaluating the value, we can use the idea of recursion to carry out post-order traversal of the expression. (3) To save the operation results to external files.)

说明：  目前的代码是一个matlab函数，它提供给定信号x[n]的短时傅立叶变换（stft）。该函数是matlab命令“光谱图”的一个替代项。功能输出为： 1）一个具有复杂stft系数的矩阵，该矩阵具有跨列时间和跨行频率； 2）频率矢量； 3）时间矢量。 为了阐明函数的用法，给出了一个示例。为了方便起见，输入和输出参数在函数的开头给出。(The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command spectrogram The output of the function is 1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows; 2) a frequency vector; 3) a time vector. An example is 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.)
