Put a model in a subsystem with matlab commands?
Background: In order to normalize Simulink models I am trying to create a Matlab function that will put the model in a subsystem if a subsystem is not the first level of my model, changes the colors of my inputs/outputs and check the name of some of my blocks. My problem is to find the most efficient way to put a mo... 23 Apr 2010 20:58

cpSelect; manual feature/point tracking
Hi everyone, I am trying to write a Matlab GUI program that allows me to manually track arbitrary points/features in a video. To go that I would add control points manually in all relevant frames of the video. Therefore, I am looking for a function or so in order to implement the setting of control points much like... 20 Apr 2010 15:57

Band Pass Filter
I have an image with 2 different surface. one is smooth another is rough... I would like to detect the rough surface...Thought of using a band pass filter to remove the low freq components and high freq noise. then by a thresholding operation and low pass filter... Anyone has example coding of the operations above?? ... 20 Apr 2010 15:56

How does the SQP algorithm deal with nonlinear functions?
Hello all! I have been using in my research the fmincon function with the SQP algorithm to successfully optimize a nonlinear function with 3 independent variables and only bound constraints, and I have been asked by a reviewer of my work to explain how exactly does the SQP algorithm deal with nonlinear objective fu... 20 Apr 2010 15:58

exporting patch data to Pov-ray
Did you figure this out yet? Exporting the patch h without color information is no problem: verts = get(h,'Vertices'); v = sprintf('vertex_vectors {\n%i,\n', size(verts,1)); v = [v sprintf('<%f, %f, %f>,\n', verts')]; v = v(1:end-2); v = [v sprintf('\n}\n')]; norms = get(h,'VertexNormals'); n = sprintf('... 20 Apr 2010 15:56
