Finding values in scattered 3D data
So here's the situatio: I have a set of 3d data, lets call it 'd', that is evenly distributed across each axis (in this case 0:.1:6), but i need to find a subset s.t. d=.75. And because i know the nature of the solution, i know the shape of the solution curve is a balloon-shaped surface. My code currently looks ... 26 May 2010 15:48

vectorisation of 3D Matrix operation
Hello! I need to speed up the execution of the following simple code. Unfortunaty I don't have an idea how to do this with 3D Matixes. (normal matrix multiplication doesn't work) ===================== % size S = (n_spec,n_React) = (10,3) % Size r = (n_cell,n_React,n_spec) = (20,3,10) % a = skal... 28 May 2010 12:38

state space form of discrete transfer function
Hello, I have a discrete transfer function for a controller 0.3778 (z-0.8824) C = ------------------------- (z-1) (z-0.9851) with sample time 0.001s. I want state space model (ie. matrices A,B,C,D) such that x(k+1) = A*x(k) + B*u(k) y(k) = C*x(k) + D*u(k) . MATLAB help says its same... 26 May 2010 14:41

contourf problem (bug?) in Matlab 7.6
I found a similar problem. In my case, contourf uses the last color to paint both the last and second to last values. So that the second to last color is not visible. Peter, did the matlab engineer get back to you with the solution? The version I am using is 7.7.0.471 (R2008b) The problem persists even if one us... 26 May 2010 13:34
