Problems sharing data between GUI's
I am currently working on a program that processes data through a series of GUI's that require data to be shared among many of the GUI's. I am trying to share one piece of data from the main GUI with the tag "File_Info" with a GUI which gives the user options for plotting a set of data. I am trying to use the UserDa... 23 Jul 2010 10:16

problem using histc
Hello, For a research project at my university i am using Matlab and I am currently facing a problem. I am trying to solve a packing problem, in which I place several pre-defined systems inside a pre-defined envelope. Both the systems and the envelope are defined as matrices. In another part of the code, the systems... 16 Jul 2010 06:38

cross validation with layer recurrent neural network
Hi All, I am trying to do sequential pattern recognition using recurrent neural network tool "LRN". Can anyone please guide me though the process of specifying input set to the LRN function and how to specify cross validation set for it. A sample script will be very helpful. Thanks in advance, Pushkar ... 16 Jul 2010 06:38

how to convert the manipulation histogram into an image?
hey guys, does anybody know how to convert the histogram, that being manipulated, to an image? well i try to make my point clearer with my code: %read an image whose histogram's will be manipulated f = imread('.....\abc.tif'); f12 = uint16(f/16); %convert the image to 12-bit [pixelcount12 gray12] = imhist(f12,... 16 Jul 2010 05:33

Custom Objects / Save then Load / Very Slow
Hi. I am running Matlab 2008b. I have written a fairly simple class which stores a few properties, has a few methods. Nothing too fancy. I then created about 10,000 objects, stored them in a cell array and saved that cell array. After clearing the workspace, I loaded the cell array. Every time I access one of th... 16 Jul 2010 05:33

reassigning values of elements in matrix
"Namo Namo" <wynamo(a)yahoo.com> wrote in message <i1ooqv$31l$1(a)fred.mathworks.com>... I need to re-assign the elements in a matrix to another set of values. The simplest, say, is to assign by order stats. For example, if I have a = [ 1 3 4 6 3 1 4 ]; By order stats, I only have 4 unique elem... 16 Jul 2010 04:28

Array Dimension as a Macro
Basically, I am looking forward to generate the code to have an array size of the global signal as a #define constant(for e.g int32 my_signal[ARY_SIZE];). To define the mpt signal for my_signal, mpt.Signal (handle) RTWInfo: [1x1 mpt.CustomRTWInfoSignal] Description: '' DataType: 'int32' ... 16 Jul 2010 04:28

Linear Fit on loglog plot
Hi, Consider the example y = x^2, for e.g. x = [1 2 3]; y = [1 4 9]; and plot loglog(x,y). Now if I use linear fit I must get a slope of 2. However the linear fit seems to work differently for the loglog plot. However if I just plot(log(x),log(y)) and use linear fit I get a slope of 2. How do I fit my data on the... 16 Jul 2010 08:47
