CZT算法的任意点数FFT变换的浮点C程序，加入MEX借口函数，从而实现matlab的直接调用！(Floating-point C program, the CZT algorithm any point FFT transform added MEX an excuse to function, in order to achieve the matlab direct calls!)

该程序演示了三角函数和双曲函数以及对数函数之间的关系，可供数学学习研究之用。 (The program demonstrates the trigonometric and hyperbolic functions and the relationship between the logarithmic functions are available for mathematics learning research.)

matlab vide the examined window into cells (e.g. 16x16 pixels for each cell). For each pixel in a cell, compare the pixel to each of its 8 neighbors (on its left-top, left-middle, left-bottom, right-top, etc.). Follow the pixels along a circle, i.e. clockwise or counter-clockwise. Where the center pixel s value is greater than the neighbor s value, write 1 . Otherwise, write 0 . This gives an 8-digit binary number (which is usually converted to decimal for convenie
