Errorbar + Subplot = fail
Hi all, I'm having a problem plotting multiple errorbar plots onto the same subplot. If I comment one out, the other will plot and visa versa, but they seem to be overwriting each other such that the two plots never appear at the same time. I'm having the same problem with scatter, so clearly the error is on my en... 3 May 2010 00:08

Plotting problem
Hi, I have some data I would like to plot. It is shear stresses as the function of flow rate. The scale of the data is quite large, x varies from 0.01 to 100 and y varies from 3e-5 to 1.5e-1. Below I have the code that I wrote but the figure doesn't seem quite right. Could someone help me that I could fit my dat... 1 May 2010 19:47

Using svmtrain to classify an image
I am trying to do a road map extraction on an aerial image and would like to use the svm family to perform a classification between 'road' and 'non-road' pixels. Can anyone give me any advice on how I could implement? Here's what I'm thinking - I pull up the image and select 5-10 known road pixels using ginput(X) to... 1 May 2010 14:18

Ok found the solution
Ok thanks for all the help but I finally found the code that shifts the x-axis in a bar graph. You simply grab the handle of the graph: bar_handle = bar(<some array>); and you change the basevalue of this graph: set(bar_handle,'BaseValue',mean(<some array>)); ;) ... 1 May 2010 14:18

GUIDE, path errors, case sensitivity errors
Hi, I keep having the same warning when I open a specific GUIDE .fig file. In my example below (on R2009b), I have a program called "balltrack2". In the declared path (in a startup.m file), I have balltrack2.fig and the associated balltrack2.m. The first line of the latter being : function varargout = balltrack... 1 May 2010 14:17
