CAT arguments dimensions are not consistent
Hello, I'm using MPT Studio to generate a controller for a system. I wrote the System Dynamics, the System Constraints, the Penalties, the Reference point, the Prediction horizon; when I press the buttom Generate Controller, the message "CAT arguments dimensions are not consistent" appears on my screen. What does it m... 24 Jun 2010 14:07

Image Analysis
Hi everyone, I'm fairly new at image manipulation in Matlab, and I've run into a problem that is confusing me. I'm trying to display an image represented by a 512x512 matrix with elements of class double. Most of the values in the matrix range from .28 -.40. I have called the matrix "pic". I want to represent this ... 23 Jun 2010 18:24

Matlab Figure won't appear docked inside Plot Tools window
I'm pretty sure this is some kind of environment problem, but I'm not sure where to look. I'm currently using Matlab R2007a on a Red Hat Linux system first with Java 1.5, and now Java 1.6. I can create a plot, but when I click on the icon for Show Plot Tools and Dock Figure, the Plot Tools window comes up, and the elem... 23 Jun 2010 18:24

Very slow update for Matlab windows
On R2010a I've been experiencing very slow updates of Matlab's windows, such as figure windows or the Matlab desktop. It can take up to 5 minutes to update the windows following what seem like simple commands (plotting, loading files, etc). Until the update happens, the Matlab windows contain a snapshot of any ot... 23 Jun 2010 18:24

Simhydraulics modelling
Hello, I am trying to model this part of my system: http://img.photobucket.com/albums/v451/Bob2Chiv/temp/modelprob.jpg in SimHydraulics. It looks to me like 1. a pilot-controlled pressure relief valve and a 2. 2-way, 2-position valve actuated by a solenoid and returned by a spring. Concerning 1. How do I make sim... 13 Jul 2010 11:59

Check for fragmention in a graph
Hi all, I need to check if removing a node causes fragmentation in an undirected graph? I now remove the node temporarily and calculate the shortest paths between all adjacent nodes. If any of the paths does not exist, it means the node causes fragmentation. This check is done in every step of my algorithm an... 25 Jun 2010 04:25

replacing loops to improve performance
Hey, I have written the following function which contains a lot of loops. Now I want to vectorize it in terms of improving the performance of the program. In general the created structure array contains 9 matrices. Every entry of the matrix is calculated by the function sim_cpv_elem_vec, whereas p and q are points ... 23 Jun 2010 17:17
