Personal Profile:

I started using MATLAB in 1985. Top of the line PCs had no hard drive, only 2e-3 GHz CPU, and 5e-4 GB RAM. Look how far we have come since then. Eventually I joined MathWorks. As an application engineer I met thousands of MATLAB users and helped them solve problems. As a quality engineer within the development organization I helped make MATLAB itself even better. Over the years I have used MATLAB to solve a wide range of technical computing problems. I enjoy exploring new problem spaces for myself and helping others learn to use MATLAB.

Professional Interests:
data analysis, visualization & algorithm development, signal & image processing, all sorts of scientific/engineering computational problem solving

27 Aug 2011 SubFuns Command-line utility to list all function declarations within a specified m-file. Author: Robert Bemis

Thanks to Jon for bringing to my attention the class method limitation.

Note that SubFuns was written years before the new MATLAB class system was developed. Rather than just hack SubFuns for this case I'd rather do something elegant and robust but not immediately (other priorities). (That would be a good opportunity to address Telmo's case too.) Meanwhile, here's a workaround.

>> SubFuns +classdir/methodfcn

Enjoy!

31 Mar 2010 Thresholding Tool Interactively select intensity level for image thresholding. Author: Robert Bemis

David James, and anyone else who sees upside-down text, please see if this applies.

01 Dec 2009 MRI Brain Segmentation Neuroimaging Case Study for seminars and webinars. Author: Robert Bemis

Note for users who get stuck by the IMVIEW error. That function was replaced by IMTOOL (years ago). In analyze_series8.m just replace all occurrences of "imview" with "imtool" (and save).

Luca, see the help for GETFRAME. The optional arguments are what you need. :)

22 Jun 2009 Thresholding Tool Interactively select intensity level for image thresholding. Author: Robert Bemis

Nathan and others, thanks for all the feedback. Some users have been tripped up by the requirement that the input must be an intensity image. RGB color is not supported. I will update the function to for this at the beginning and stop immediately with a more helpful error message.

17 Jun 2014 Light Bartlein Color Maps Generates one of four colormaps using schemes proposed in technical literature Author: Robert Bemis Orloff, Nathan

Really excellent. If you want to make a black background.

colormap([0,0,0;(lbmap(121,'RedBlue'))])
colorbar

Really great work. And matlab should make colorblind colormaps available for all there plots.

Hey Robert Bemis, I was also experiencing the inverted text bug. I followed the steps listed in the link you provided and it corrected itself. Thanks for the insight!

Also this tool is fantastic!
