08 Mar 2014 Flappy Bird for MATLAB MATLAB replica of the viral mobile game "Flappy Bird" Author: Mingjing Zhang

It is hard to believe you took the time to make this. Funny! :)

Interesting! :)

04 Mar 2014 Smooth Robust Differentiators numerical differentiation with noise suppression Author: Jason Nicholson

Help would be appreciated for some one well versed in numerical analysis. Right now the coefficients used in the formula (see documentation) get large quickly. Proper care needs to be taken to minimize the effect of round off error. Best practices or rearranging of the equations would be beneficial. I have even thought of hard coding the coefficients of N<=101 into robustDiff after calculating them with variable precision arithmetic. However, I am not sure what this would be beneficial. I could use advice on what to do here.

04 Feb 2014 Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays. Author: Anthony Kendall

I have used this function over and over. I have referred to many times when solving different problems. This is great work! I am very grateful for your posting of count_unique!

04 Feb 2014 iSignal 3.4 Interactive smoothing, differentiation, peak sharpening and measurement of time-series signals. Author: Tom O'Haver

Tom, thanks for the update! It works now.

Your ideas about "i" and "j" have been addressed in the 29-Jan-2014 version.

17 Jan 2014 Matlab Style Guidelines Cheat Sheet One page summary of the "MATLAB Programming Style Guidelines" Author: Jason Nicholson Vernon, Gregory

@Volker -- I agree. I use ii, jj, kk as my short scope variables instead.

16 Jan 2014 Matlab Style Guidelines Cheat Sheet One page summary of the "MATLAB Programming Style Guidelines" Author: Jason Nicholson Volker

Just don't use "i" or "j" for short scope variables - they are predefined as the imaginary unit sqrt(-1) in matlab.
