What is the syntax for this atan2 formula ?
I tried almost everything, but with no success. Any ideas ? Here's the link for the formula in a jpg format : http://forum.bgu.co.il/uploads/monthly_06_2010/post-24033-12765479851708.jpg Thank you ... 15 Jun 2010 01:06

Finding Gaussian Basis
Hi! I am trying to find the Gaussian Bases of an image, may be in the form of frequency domain coefficient. Is there any existing program widely used? Else can anyone give me some hint? Sincerely, DRN ... 15 Jun 2010 01:06

fmincon infeasible starting point
Hello, I have a question about fmincon. If the user-supplied starting point is infeasible, but assuming the problem is feasible, what does fmincon do? Does it try to find the nearest point that's feasible without consideration of the objective function? Thanks wly ... 15 Jun 2010 09:47

Non anisotropic wavelets
Usually when one doing wavelts transform in 2D it will use wavelets - psi(x)phi(y) phi(x)psi(y) psi(x)psi(y) I wanted to calculate 2D transform in basis psi_{i,k}(x) psi(l,m) (y). Does anyone know how to do it? Is there standad matlab routine for it? ... 14 Jun 2010 19:35

Edit Text Box: Fixed Value
Hi, I want the user to be able to copy and paste data from my GUI. Right now, I'm outputting data as a label. However, the user can't select and copy the label. Therefore, I'm hoping to switch to edit boxes. A couple problems I have though, is: 1) Changing the border of the edit box to match my background. 2) C... 15 Jun 2010 05:25

Problems with periodization
I am trying to implement db4 DWT with periodazed wavelets. However,my results is slightly different what matlab does. As I noticed my code works fine for one-level decomposition,but and higher level I've got details coefficients different from matlab code. Approximation coefficients are calculating fine. My algori... 14 Jun 2010 19:35

cell2mat with different data types
Hi all, I've imported some data that comes in cell format, some of it is classified as 'int32' and others are 'double'. I need to convert this to a matrix, however, because of the differing formats (though all columns are numbers) it won't let me do it. I'd be happy converting everything in the cell to 'double' form... 14 Jun 2010 20:42
