Independent Component Analysis with Reconstruction Cost

该本书籍非常适合MATLAB初学者学习，书籍的内容涵盖的面很广，包括对软件的安装，界面的介绍，MATLAB语言，数值计算，程序设计，符号运算，simulink仿真的介绍。这本书的内容，既详细又有许多例子为辅来解释软件的各项功能。对于需要MATLAB作为科研工具的学者们，这是一本非常好的工具书。对于想学习MATLAB软件的同学们，也是一本非常好的学习教材。(This book is ideal for beginners to learn MATLAB, surface content covers a wide range of books, including the introduction of the installation of the software, interface, MATLAB language, numerical computation, program design, symbolic computation, simulink simulation presentation. Contents of this book, there are many examples of both, supplemented by detailed to explain the features of the software. The need for MATLAB as a research tool for scholars, this is a very good tool. For those who want to learn MATLAB software for students, but also a very good learning materials.)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )
