Here’s a (incomplete) list of code, applets, and small software I wrote for ease of research or life. I’ll publish more from time to time when I have time to arrange things to publicize. :)

Semilog x-Axis Bar Plot for MATLAB

I found it extremely inconvenient without this functionality sometimes, so I decided to just write one myself. Help info is contained in the .m file. Given proper input, it produces bar plot on semilogx axis with given center points and values. “Proper” means you’ll have to ensure the input are approximately equal-spaced in the log domain, or the output may look weird. Here’s what it might look like.
>> x=[1 2 4 8 16];
>> y=rand(1,5);
>> semilogxBar(x,y)
