已知离散的坐标数据，利用这些坐标点进行椭圆拟合的程序(Known coordinates of discrete data points to use these coordinates ellipse fitting procedure)

matlab在天线原理中的应用，求出辐射电阻，方向系数，E面方向图 ，HPBW(matlab antenna theory, find the radiation resistance, directivity, E-plane pattern, HPBW)

image and signal processing are used mostly right now. these programs is related to image processing. Image negative is used for the getting the negative image of the original image. and contrast stretching is for the give the middle value. Fast Fourier Transform program is used for the getting FFT of the signal.
