代码说明:

   Designs an FIR filter given a desired frequency response H_des(w). The design is judged by the maximum absolute error (Chebychev norm). This is a convex problem (after sampling it can be formulated as an SOCP). minimize max |H(w) - H_des(w)| for w in [0,pi] ( where H is the frequency response function and variable is h (the filter impulse response). )

    相似度算法的实现, 在利用支持向量机进行模式分类的时候,有时需要考虑到实时性,为了提高实时性,则利用相似度算法减少样本集个数,从而减少训练时间和支持向量的个数,使得建立起的向量机实时性提高。(Similarity algorithm, support vector machine in pattern classification, it is sometimes need to take into account the real-time, in order to improve real-time, the use of similarity algorithm to reduce the number of sample collection, thus reducing training time and the number of support vectors, improve the real-time of established Vector Machines.)
