Least squares with ill-conditioned mxn matrix
Hi, I'm trying to make a function where I somewhere use least squares with the command: b = pinv(A) * B I already know the true b vector and the estimated A matrix is the same as the true A matrix but some results of the estimated b are far away from the true. A is a very ill-conditioned matrix (rcond(A) gives me n... 15 Jul 2010 04:28

Solving linear programming equations using linprog
Hi, I'm implementing an Call Admission Control algorithm using Markov Decision Processes. In the end I have to maximize the following objective function: Maximize: sum_x(sum_a(T(x,a)r(x,a)H(x,a))), where H is feasible CAC policy Subject to: sum_x(sum_a(T(x,a)H(x,a))) = 1; sum_a(H(y,a)) = sum_x(sum_a( P(y|x... 13 Jul 2010 07:36

Creating mesh and using contourf for temperature
Hi all I wrote a matlab code to find 2D temperature distribution in a plate that is 0.4m wide by 0.7m tall. There are 40 nodes all together. I used the energy balance method and determined the temperature on each node using the matrix inversion method. Now I have temperature of each of the 40 nodes in T, and wish to... 20 Jul 2010 03:45

Possible Issue with Jan Simon's "Shuffle" Program
Hi Everyone, I have applied Jan Simon's "Shuffle" program in a simulation I am working on right now. Part of the simulation is a loop n times, where at each loop a random order of x numbers is supposed to be generated. But, I have noticed something, which I wonder if others, ideally Jan, can clear up: For a given... 14 Jul 2010 19:49

simulink subsystem address "not valid"
I'm trying to use the "set_params" function to alter the value in a gain block in simulink. I've read it won't work unless I load the model first, so I'm trying to use the "load_system" function now. When I have this subsystem open in simulink, the file address at the top of the window reads something like: ... 13 Jul 2010 19:43
