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

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.

07 May 2014 Dielectric characterization by microwave cavity perturbation A custom toolbox and example code to measure complex permittivity by microwave cavity perturbation Author: Nathan Orloff

Let me know if there are any problems with this. I will update it regularly.

24 Mar 2014 Text progress bar This function creates a TEXT progress bar in your command window. Author: Paul

superb

24 Mar 2014 WORKBAR Efficient and stylish alternative to WAITBAR. Author: Daniel Claxton

I love this function. But it uses the image processing toolbox. I wish it didn't.

07 Feb 2014 Fit 2D Gaussian with Optimization Toolbox Fit a 2D rotated gaussian. http://en.wikipedia.org/wiki/Gaussian_function Author: Nathan Orloff Orloff, Nathan

fitresult = fit parameters used to generate the fit.

zfit = the z values of the fit

fiterr = error in the fitparameters assuming a confidence interval.

zerr = error in the z values assuming the uncertainty in the fit paramteres

resnorm = residual

rr = reduced chi-squared.

30 Jan 2014 Fit 2D Gaussian with Optimization Toolbox Fit a 2D rotated gaussian. http://en.wikipedia.org/wiki/Gaussian_function Author: Nathan Orloff Olhado

This bit of code is doing exactly what I want I think but I wondering if it might be possible for the Author to expand on the meaning of the values the function outputs or point me in the direction as to where I can find the answer. Thanks a Ton

29 Jan 2014 Histogram fitting Probability Density, Counts, Frequency A cleaned up version of histfit that outputs data Author: Nathan Orloff Orloff, Nathan

Oh it doesn't output the object and it makes a graph of counts instead of probability density. So that was driving me a little crazy.
