optimising a section of the ert generated code for execution on a Ti DM6437
I've made an algorithm to do image (video) segmentation on a dm6437evm. However, looking at the code (see below) I've noticed some inefficiencies in the way that the video is handled and want to create my own source code for these functions. There seem to be a number of ways of approaching this and I'm not really sure ... 22 Jun 2010 13:48

GUI save mouse-clic coordinates in a matrix
Hi, I'm using a GUI to open figures, clic on points of interests. I can see the ccordinates of that points on a box in the gui, but can not use them. How can save the coordinates, to use them (it's fine a matrix, a text file or whatever). Thanks, Ila ... 22 Jun 2010 13:48

Simulink debugging
When I try to update my model diagram, I get an error that reads : "Attempt to reference field of non-structure array" with an unknown source. I can't use the simulink debugger to find the problem because it returns the same error. How can I pinpoint the location of this error? ... 22 Jun 2010 13:48

timed graphing of a figure
Hi, I would like to graph several graphs on one figure, I was wondering if I can time the appearance of each graph? Also, if the timer function is one of the way to do it, is there another way other than using timer? Thanks! Jen ... 22 Jun 2010 14:55

Discrete Sampling in Simulink... bizarre behaviour
Hey, I do not understand the following behaviour: - Simulink Model: In -> Out [1] In imports the data from the workspace structure 'simin', and exports the data into the vector yout as you can see in [2] - In the workspace the structure simin is build as follows: Fs = 4e6; simin.signals.values = read_complex... 22 Jun 2010 14:55

|| and && question
This is my code y=size(C); u=[4 1]; if y(1:1)~=u(1:1) || y(1:2)~=u(1:2)%any(y)~=size([0;0;0;0]), error('MATLAB:quat2angle:InputSizeMismatch','C must be a 4x1 matrix.'); end When I run: quat2angle([4;3;4;0]) I get: ??? Operands to the || and && operators must be convertible to logical scalar values. ... 22 Jun 2010 13:48

slope of edge
Hello Friends, I am trying to gauge the blur of an edge. For eg an example profile of an edge is as stated - [133,131,127,129,127,129,120,105,90,82,85]. The trace is as shown above . The decay is what I am trying to gauge. In very blurred images the length of the decay is greater that when the edges are sharp. C... 22 Jun 2010 12:41

Fit Distribution to Data
Hello I have plotted two different data sets. http://yfrog.com/0afitdistributionforblueap Blue and Red data sets For every different value on axis x I have taken only 10 measurements as it takes so much time for the experiment to run. I would like to fit two distributions for these two data sets. One for each one... 5 Jul 2010 05:38

How to use my own transfer function in NNToolbox
Hi, I have created my own transfer function "myTF.m" and I want to use it in a neural network generated by NNToolbox, i.e. with newff. I want to use my own transfer function instead of those existing ('tansig', 'purelin', ecc.), i.e.: net.layers{i}.transferFcn = 'myTF'; What I have to do in order to use 'myT... 22 Jun 2010 18:15

DISCRETE SINE WAVE GENERATOR IN SIMULINK
I have been trying to use the discrete sine wave generator in SIMULINK. It asks you to specify a frequency, but no matter what you put in this block it still outputs only what amounts to the baseband representation of the sine wave at the phase offset you specify. Is there something wrong with this block or am I misi... 22 Jun 2010 12:41
