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.

Great function!

One issue on R2014a :
load heatmapData
clf
heatmap(spreads_small);

yields

Error using hg.axes/set
The name 'TickLabelInterpreter' is not an accessible property for an instance of class 'axes'.

Fix:

comment out line 331 in heatmap.m:

% set(p.hAxes,'TickLabelInterpreter','none');

17 Jul 2014 Electricity Load and Price Forecasting Webinar Case Study Slides and MATLAB® code for the day-ahead system load and price forecasting case study. Author: Ameya Deoras Irakli

Hello. I downloaded these files and compiled LoadForecast.m as class and other files and folders as helper files and folders. Everything went OK and compiler generated .dll and .bas files. I linked those bass files in .xlsm file, but when I press compute forecast it doesn't show "Neural Net" (files with 0-s) it shows only tree model result.

I don't know if it is relevant, but in holidays file dates are written like this: 01.01.2007, but matlab needs format like this 01-01-2007. I compiled default files and then programmatically changed "." to "-" in dates, still "Neural Net" doesn't work in both cases.

Please help me. I will appreciate any response!

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')
