08 Apr 2014 Free-free beam FFbeam.m script computes Free-free end beam mode shapes and natural frequencies Author: Sulaymon Eshkabilov

I have not checked the calculations, but there seems to be an error: It returns the same frequency for modes 6 and 7 for example #1.

03 Mar 2014 singlebox Flexible box plot creation (allows unequal sample sizes and displays sample size and outlier index) Author: Dennis

I like the fact that the function shows (and returns) the indizes of the outliers.

Suggestions for improvements:
- adjustable whisker size (now hardcoded to the boxplot standard of 1.5 - at least this fact should be documented)
- better display of outlier indizes - in the current version, numbers overlap and or thus often unreadable

03 Jun 2013 fitExponential.m Fitting with single exponential curve in the form of: yFit = yInf + (y0-yInf) * exp(-k*(x-x0)) Author: Jing Chen

Nicely does its job. Would be perfect for my use if it allowed an additional weight vector.

16 Apr 2013 High-Low plot or percentile (5 and 95) plot This plot is the surrogate of boxplot. Author: Taesam Lee

This seems to be a derivative of boxplot.m, even with "Copyright 1993-2005 The MathWorks, Inc." inside. I doubt you can put this under the BSD license.

15 Feb 2013 Fast and Robust Curve Intersections Computes intersection points of two curves. Author: Douglas Schwarz

Does what it should, no problems so far.

14 Nov 2014 colormapline - color-changing 2D or 3D line Plot a 2D or 3D line using a specified colormap. Author: Matthias Hunstig Matteo Niccoli

To get the lightness for jet in my previous snippet, I used this code:
lab2 = colorspace('RGB->Lab',jet(256));
and this submission:

14 Nov 2014 colormapline - color-changing 2D or 3D line Plot a 2D or 3D line using a specified colormap. Author: Matthias Hunstig Matteo Niccoli

Works well for me. For eample I used this code:
figure;
j=jet(256);
h=colormapline(1:1:256,lab2(:,1),[],j);
set(h,'linewidth',2.5);
to get the first figure in this post:
