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, then 'X' is of size (nh) times (nx+nh-1). Then 'h*X' is same as conv(x,h). This does not depend on the in built command 'TOEPLITZ'.

This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal... D = decimmtx(x,N) decimates the given signal by a factor of N. [D,y] = decimmtx(x,N) gives D as well as the decimated signal y

The signals presented here can be used in demonstrating how the signal varies when the operation is made on either independent variable or dependent variable. The parameters can be varied to have a feel of the variation. Example(1): rect(1,2) plots the rectangular signal of amplitude 1 and a width of 2. Example(2): rect(1,2,3) plots the rectangular signal with amplitude 1 width 2 and shift of 3. Example(3):rect(1,2,0,2) plots the rectangular signal amplitude 1 and width of 1 because of the scaling by a factor of 2.
