Matrix Binary Help
Hi, I am stuck in a very basic step for a binary image, I have 240 row and 113 column binary matrix that i need to do some manipulation with, what is need to do is to first slice the matrix in half, which is easy enough, i used this to code, [m,n]= size(K); % get the row column size of the image X = 1:n; ... 9 Jul 2010 02:53

Figure initial position
Hello. Now, I'm very nervous about the initial posiition of figures. I know that figure position can be changed using some commands. However, I just see my figure on screen only using 'plot' command but, they always posted on the out of screen so I cannot see them. How can I change the setup of initial figure... 8 Jul 2010 04:48

Number of wavelet coefficients in each level of decomposition
Dear All, I am wondering the wavelet decomposition implementation in Matlab. In wavelet decomposition using the command "wavedec", the number of coefficients in each level should be (length of original signal)/(2^j) where j = 1,2,3,....n For example, if the length of the original signal is 3600, it should be j = ... 8 Jul 2010 23:38

Convert daily time series to monthly
A problem working with a time series. I have a vector of dates (imaginatively titled 'dates'), more or less covering all business days over a time period of a few years. I use the date series as inputs to a dialog box, for the user to choose start and end dates that define a desired subset. (So far so good.) Rather ... 8 Jul 2010 10:14

identification AR filter coefficients
I try to identify AR filter coefficients. I only know the frequency answer Y of the filter H Y = H (f); f is the frequency vector. I try with this command: h = idfrd(Y, f, 1/4); Coeff = iddata (h, [], 1/4); Y is the frequency answer vector and f is the frequency vector Length(Y) = length (f); When I d... 8 Jul 2010 08:02

Help on image processing
I have the code to split a 10bit double frame image to two 8 bit tif images.But i now need to merge them back into a single 10 bit image. I read those 10 bit images using imread and divide them by 4 to get two 8bit images. Does neone knows how to do this? With regards Raj ... 8 Jul 2010 15:51

plotting loglog plot with Zero-Order-Hold
Hi, I want to plot 2-D log-log plot with Zero order interpolation. I know that stairs can plot ZOH but how to use it with loglog.. or is there any other way? (I can take log of data and then plot with stairs, but then how to get the points in terms of 10^x, as the points in axis would be in numbers (power of 10) only)... 8 Jul 2010 03:43
