说明：  数学建模的各种程序，数学建模书上的各种程序，全部编译通过了，可以直接使用(Mathematical modeling of various processes, mathematical modeling procedures on the books, all compiled by, and can be used directly)

Save the image in several formats and calculate their mean square error

利用双线性Z变换设计巴特沃斯和切比雪夫I型IIR数字滤波器，包括低通、高通、带通、带阻四种形式。使用者只需指定通带、阻带的边缘实际频率及相应的衰减，便可输出数字滤波器 的级联形式的各子系统分子、分母的系数，并输出其幅频和相频响(Bilinear Z transform design Butterworth and Chebyshev Type I IIR digital filters, including low pass, high pass, band pass, band stop four forms. Users simply specify the passband edge frequency stopband actual and corresponding attenuation subsystems can form molecular cascade output digital filter coefficients of the denominator, and the output of its magnitude and phase frequency response)

code give you discrete points along the curve

it is to explain gibbs phenomenon

it is a matlab code for non linear programming.it calls penalty method.
