Averaging and replacing elements in a matrix
Here is what i have so far: A = [123; 43; 89; 100; 43; 67; 98; 43;]; B = [12; 9; 8; 2; 33; 6; 5; 18;]; C = [A,B] The output is thus, C = 123 12 43 9 89 8 100 2 43 33 67 6 98 5 43 18 I want to write a script that reads through A to see if there are any repeat... 15 Apr 2010 11:22

display figures in matlab distributed computer server
Hello everyone, when I run my program from my laptop in a remote cluster of 16 processors, The program is running in the cluster and I would like to display the figures of my program. If I run the program in my laptop everything is fine, the command plot works perfectly, but when I run the program in the cluster (... 12 Apr 2010 12:32

Basic question on lists
I have a minute problem going on. I'm wanting to make lists in .txt files, with headers and columns. I get the headers and i get the columns, but the numbers themselves are not doing what i want them to. Instead of putting one variable in one column, it runs the first variable across the first row, and continues on ... 12 Apr 2010 12:31

Mosfet's operation in a flyback converter
Hello, First of all i am using Matlab 2007b and I am trying to simulate a flyback converter (in Simulink) using the well-known topology one can find into Mohan's bibliography. However, if i choose to have a mosfet for the switch operation, there seems to be a extravagant losses on it (few Volts), which by the use o... 12 Apr 2010 12:31

Estimate distribution based on histogram data
Dear List, I have mortality data by age groups (below 1, 1-4, 5-9 etc.) and I would like to fit a curve to transform the grouped data into yearly data. How could I do this? I tried ksdensity but I have no discrete data, only grouped. Sorry for this, but I couldn't find any answers online. Thank you very mu... 12 Apr 2010 11:24

Mixed format strings
Hi I have a tricksome problem (for me anyway) I am using fgetl to read lines from a text file. However I only want the number parts of it. Is there a way to just extract the numbers before the ascii chars at then end and then use str2num to make a matrix? .0124 200 900 260 600 .2140 .1586 .3179 80.... 13 Apr 2010 15:04

Durbin Test
Hi, I need to perform rank test to test the null hypothesis of no difference among treatments (I hope this makes sense: think about the Friedman test or the Durbin test). I have one problem: the experimental design is incomplete and is not balanced. Can I still use the Durbin test? I know it works for incomplete... 12 Apr 2010 11:24

Drawing 3D Fractal trees Oak, Poplar Yew etc.
Hi all I am currently working on a shading model for a PV array and need to model some 3D trees. I could use cylinders/spheres etc but it should be possible to generate trees using a fractal like approach. Indeed there is some 2D code existing to do this. 3D trees seem also to exist in some commercial VR packages, but... 12 Apr 2010 11:24

Problem with interp3
Peter, I think you mis-interpreted the error message here. The error message states that the _lengths_ of X Y and Z must match the _size_ of V. That is what Prashant was trying to show with the notation you did not understand. To clarify for others reading this post, look closely at the help for interp3: VI ... 12 Apr 2010 10:17
