cosine_filter
一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

bandelets_toolbox
This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the
major concepts and properties of these orthogonal basis. It
does not contain any coding scheme, nor a fast implementation(This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the major concepts and properties of these orthogonal basis. It does not contain any coding scheme, nor a fast implementation)
