10 Jul 2014 Table Breakpoint Optimization A set of tools for finding the best way to reduce the size of a table. Author: Tucker McClure

Excellent! Works great for approximating a curve with piecewise linear functions

05 May 2014 Midi Tools This code allows you to read and write midi files. Author: Christine

For those running into problems with java, you can also dynamically add the JAR to MATLAB's java path by executing the following. This is less of an effort than changing classpath.txt

javaaddpath('C:\MidiLibrary\KaraokeMidiJava.jar')

where C:\MidiLibrary in this example is where the JAR is located.

15 Feb 2014 Customizable Heat Maps Visualize data as a heatmap with many customizable options. Author: Ameya Deoras

Karin, thanks for catching that oversight. Jonathan, technically "iscellstr" is correct but since the text function allows empty numeric values as the string, I will change it to iscell.

The changes will be in today's update. Thanks!

Hi everyone. Thanks for the comments/feedback. I have updated the function with fixes and new features:
* It now correctly handles the labels for small matrices with labels.
* There are two options minColorLevel and maxColorLevel that allow you to specify how the data range maps to the color range. This is useful when comparing heatmaps and ensuring the same color-data mapping between heatmaps
* There is now a nanColor option that allows you to specify a special color for missing data elements.

Izi, that error seems to suggest that you are calling the genPredictors function without any inputs. “data” is a required input for the function and needs to be specified. See loadScriptNN for an example of how to use this function.

01 Jul 2014 Intelligent Dynamic Date Ticks Create plots with date-friendly data cursors and smart date ticks that scale with zooming & panning. Author: Ameya Deoras Queffurust, Aurelien

@Anuraag : you may have this error if figH is not the handle of a figure but a handle of a uipanel for example

TO verify this : type get(figH,'Style')

11 Jun 2014 Customizable Heat Maps Visualize data as a heatmap with many customizable options. Author: Ameya Deoras Andre

Thank you very much for this awesome function!
But I'm actually having a problem with the min/max color value of the ColorBar. When I try the following code:

x=randn(3,3);
h = heatmap(x, [], [],'%0.4f', 'Colorbar', true, 'MinColorValue', 0.0, 'MaxColorValue', 1.0, 'Colormap', 'autumn', 'Colorlevels', 10, 'Gridlines', '-', 'FontSize', 15, 'UseFigureColormap', false);

It returns an error:
Subscript indices must either be real positive integers or logicals.

Error in heatmap>plotHeatmap (line 235)
p.cdata = reshape(p.Colormap(p.cdata(:),:),[size(p.cdata) 3]);
Error in heatmap (line 128)
p = plotHeatmap(p, mat); % New properties hImage and cdata added

And plots nothing. Am I doing something wrong?

Hi everybody,
I am having trouble downloading the data from
www.iso-ne.com
can somebody help me with this problem?
Maybe somebody can upload it for me or send it to me?

that would be very nice
thanks in advance
