Matrix Operations Worksheet

[h,varargout]=plotColumns(data,varargin)plots columns of a matrix as if each column is a time seriesUSAGE:plotColumns(data);[h] = plotColumns(t,data);[h] = plotColumns(t,data,{colors});[h] = plotColumns(t,data,'plotopt');[h] = plotColumns(...,'plotopt');[h] = plotColumns(...,{colors});

The function generates sequency(Walsh) ordered Hadamard matrix useful for image processing, signal processing, genetic algorithms etc.

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h). If 'x' and 'h' are row vectors,...
