Matlab Builder JA error in MAC OS X
Hi, I have created an application with MATLAB 2009a Compiler on an Intel Mac. To run the application I need to set the DYLD_LIBRARY_PATH as specified in the documentation. When I Try to instantiate a class, for example: bs = new BlackScholesClass(); I get the next error: java.lang.NullPointerException a... 1 Apr 2010 14:37

Integration square
Hi.. I have an equation in the following format. y=(Cosh4x+cos4x-sinh4x-sin4x)^2 I need to find integration of y for the limit 0 to 1. Can you please help me with the integration command to integrate this square term. Thanks in anticipation Regards, Rajkumar R ... 5 Apr 2010 07:11

Missing a couple of basic (and very necessary) features in containers.Map
Almost all of my Matlab work is done using arrays, sparse arrays and cell arrays. Only recently have I found a natural application for containers.Map, and I was pretty excited to explore this relatively new tool. However, a few missing features are making it hard to work with. First, there's no way to create a new, ... 2 Apr 2010 11:29

Vectorize This
How would one vectorize the code below? It seems like it should be a fairly simple thing to do... % The matrix 'A' is a 3D data cube of size N x N x N L = zeros(N^3,4); ind = -250*delt:delt:250*delt; for di=1:N for dj=1:N for dk=1:N L(di,:) = [ind(di),ind(dj),ind(dk),A(di,dj,dk)]; end ... 1 Apr 2010 15:45

Problems with loading file
Hi, I'm having soming trouble to define correctly how to load a file. Stored in "a" i have a string Stored in "b" i have a number I want to load a file with the name "a"_"b".txt For example: in "a" there is the word "car" in "b" there is a value 500 i want to load the file "car_500.txt" How should I d... 1 Apr 2010 17:59

Pause analog input
Hi, Is it possible to pause an analog input and then resume the data acquisition with a callback (or whatever) without clearing the data engine like when using stop(ai)? For example if I want to pause the acquisition after 4 seconds and then resume the acquisition after a couple of seconds with some sort of callb... 1 Apr 2010 12:22

Making C++ objects persistent between mex calls, and robust.
Hi all I'd like to revisit the question of how to make C++ objects persist between mex calls safely. This topic has been discussed before in the following thread: http://www.mathworks.com/matlabcentral/newsreader/view_thread/156994 (and many others), without a perfect solution (IMO). The aim is this: given a C+... 1 Apr 2010 12:21

From CG algorithm to ORES algorithm?
Do anyone know how to obtain ORES algorithm (Orthogonal Residual Method) starting from CG algorithm (Conjugate Gradients)? ORES: x0 ∈ C^N , r_0 = b − Ax_0 ρ(0)=||r(0)||, q(1) = r(0)/ρ(0), β(0) = 0, q(0) = 0 f or i = 1, 2, 3, . . . v = Aq(i) a(i) = q(i)^* v v = v − q(i) a(i) &#8... 1 Apr 2010 12:21
