uiinspect
After several years in which I have mentioned my uiinspect utility in posts, I figured it is high time to actually describe this utility in detail. uiinspect in action (Java, HG, COM) uiinspect,...

Getting default HG property values
All Matlab’s Handle Graphics (HG) property have default values. These values are used unless we specifically override the property value. For example, in R2012a, Matlab figure handles have 62...

Customizing figure toolbar background
In one of my projects, I needed to present a radar (polar) plot. Such plots are usually drawn on a black background and I wanted all the plot controls to blend into this background. Matlab figure...

Matclipse – Eclipse-Matlab interface
I am extremely pleased to host guest blogger Christopher Albert. Chris and his colleagues created and maintain the enormously-interesting (IMHO) and complex Matclipse project, which connects Java’s...
View ArticleHandle Graphics Behavior
Matlab’s Handle Graphics (HG) have been around for ages. Still, to this day it contains many hidden gems. Today I discuss HG’s Behavior property, which is a standard undocumented hidden property of all...

HG’s undocumented parameters interface
Continuing last week’s article on Matlab Handle Graphics’ (HG) undocumented Behavior functionality, today I describe another undocumented aspect of HG. Some of the low-level HG functions, such as line...

JTattoo look-and-feel demo
Three years ago, I wrote an article about modifying Matlab’s look-and-feel (L&F, or LnF), using Java’s built-in support for replaceable LnFs. To date, that article has 27 comments by 13 different...
View Articleishghandle’s undocumented input parameter
Two weeks ago I wrote about Matlab Handle Graphics (HG) undocumented acceptance of structs as input parameter to some plotting functions. Continuing in a related matter, today I expose an undocumented...

Parsing mlint (Code Analyzer) output
Mlint, Matlab’s static code-analysis parser, was written by Stephen Johnson (the original developer of the enormously successful lint parser for C/C++ back in 1977), when he was lured by MathWorks in...
View ArticleSetting class property types
When I wrote about the undocumented aspects of classdef properties half a year ago, I did not expect to learn of another major undocumented aspect in Matlab’s class-object system. last month I...

Improving fwrite performance
Readers of this blog are probably aware by now that I am currently writing my second book, MATLAB Performance Tuning (expected publication date: early 2014, CRC Press). During my work on this book, I...

Improving save performance
Two weeks ago I posted an article about improving fwrite‘s performance. fwrite is normally used to store binary data in some custom pre-defined format. But we often don’t need or want to use such...

HG2 update
Exactly three years ago, I posted information (here and here) about Matlab’s upcoming new graphics engine, so-called HG2 (Handle Graphics version 2). At the time, I was sure that HG2 was just around...

Displaying animated GIFs
Displaying images in Matlab figures has always been sort-of awkward. We need to read the image file into a Matlab matrix (possibly with accompanying colormap), then create an invisible axis in our...
