one-sided 2D inverse fourier transform
Hi, I try to solve the Taylor-Goldstein equation for gravity waves. The second order differential equation is solved in frequency space. To get a solution in physical space I need to do a one-sided 2D inverse fourier transform. I thought it seems reasonable considering only positive frequencies while setting all... 26 Jul 2010 07:15

Changing the dimensions of a matrix
Hi all, When I open an image file with pic = fread(picfileid), I want pic to have dimensions which match the height and width of the image. I wonder what a smart way to do this would be in Matlab. I.e., how do I transform [1 2 3 4 5 6] to [1 2; 3 4; 5 6] Thanks ... 26 Jul 2010 11:37

Gaussian Distribution
Hi, I am trying to write a script that generates a 2D Gaussian distribution that has a user specified encircled energy within a user specified pixel width - for example 80% energy within a radius of 3 pixels. I have generated a gaussian and observed the effect of changing sigma and ensquared energy and also look... 26 Jul 2010 05:07

Power law curve fit through a specific point
Hi all, I have some data in matlab that I would like to fit with a power law model. The complication is that I want to force the model to pass through a given point ( i.e. x = 37, y = 0). Maybe this is not possible using a power law since 37^a will never equal exaclty zero for any constant a. It is possible t... 31 Jul 2010 07:28

Creating a map. How-to
Hello. I would try to explain what I would like to implement so to suggest me what to try out. I would like to create an area of X*X km that would be used to "Simulate" an area map (eg. city's area, suburban area). -X would be a parameter so I do not want it to be fixed -In this map I would like to place use... 26 Jul 2010 04:03
