Matlab’s button uicontrols (pushbutton and togglebutton) are basically wrappers for a Java Swing JButton object. This will be the first in a series of posts showing how Matlab uicontrols can be customized in ways that you may never have thought possible. Probably the simplest undocumented customization is the control’s acceptance of HTML and CSS Strings: tooltip = '<html>HTML-aware<br><b>tooltips</b><br><i>supported'; labelTop= '<HTML><center><FONT color="red">Hello</Font><b>world</b>'; labelBot=['<div style="font-family:impact;color:green"><i>What a</i>'... ' <Font color="blue" face="Comic Sans MS">nice day!
']; set(hButton, 'tooltip',tooltip, 'string',[labelTop '<br>' labelBot]); Button with HTML label and tooltip For more powerful customization, we need to access the control’s underlying JList object. >> jButton = java(findjobj(hButton)) jButton = com.mathworks.hg.peer.PushButtonPeer$1[,0,0,...] Please let me know of any nice customizations in your Matlab applications.

In this post I will be showing how to produce a publication quality figure using MATLAB (2007a). To fully appreciate the content presented here you will need some working knowledge of MATLAB, meaning that you should know how to create a basic plot. If you need some help in this department you can reference this Guide from MathWorks. But, if you’re ready to create a publication quality figure (i.e., one that doesn’t look like it was made in Excel), then keep reading.
Suppose I am raising two different species of fruit flies in my lab, and once a day for 10 days I measure the size of both populations and record the numbers in two vectors called Species1 and Species2. Now I want to visually compare the growth of the two populations over the 10 days so I use the following basic plotting commands h1 = plot( Days, Species1 ); hold on; h2 = plot( Days, Species2 ); *Note that the vector ‘Days’ contains the numbers 1 through 10 which represents the days over which the experiment took place. Creating Movies in MATLAB. Carl Scarrott This set of instructions detail how to create movies in MATLAB 5.1, convert them to the standard movie format MPEG and how to play them. Limited knowledge of MATLAB or the MPEG format is assumed. This code has not been verified for any other MATLAB version. How to create MATLAB movies 1) Open MATLAB figure window: >> fig1=figure(1); 2) Resize the figure window to size of movie required. 3) Record the size of the plot window: >> winsize = get(fig1,'Position'); 4) Adjust size of this window to include the whole figure window (if you require the axes, title and axis labels in the movie): >> winsize(1:2) = [0 0]; 5) Set the number of frames: >> numframes=16; 6) Create the MATLAB movie matrix: >> A=moviein(numframes,fig1,winsize); 7) Fix the features of the plot window (ensures each frame of the movie is the same size): >> set(fig1,'NextPlot','replacechildren') 8) Within a loop, plot each picture and save to MATLAB movie matrix: >> movie(fig1,A,30,3,winsize) >> save filename.mat A or in MATLAB:
How to parse a string? (Simple question) - comp.soft-sys.matlab. MATLAB | blinkdagger. MATLAB GUI Tutorial - For Beginners | blinkdagger. Why use a GUI in MATLAB? The main reason GUIs are used is because it makes things simple for the end-users of the program. If GUIs were not used, people would have to work from the command line interface, which can be extremely difficult and fustrating. Imagine if you had to input text commands to operate your web browser (yes, your web browser is a GUI too!). It wouldn’t be very practical would it? In this tutorial, we will create a simple GUI that will add together two numbers, displaying the answer in a designated text field.
This tutorial is written for those with little or no experience creating a MATLAB GUI (Graphical User Interface). Contents Initializing GUIDE (GUI Creator) First, open up MATLAB. You should see the following screen appear. You should now see the following screen (or something similar depending on what version of MATLAB you are using and what the predesignated settings are): Creating the Visual Aspect of the GUI: Part 1 Two Edit Text components. MATLAB Graphics. MATLAB graphics can help you see the big picture in your data.
It's easy to plot functions or scattered data, to sketch geometric models, to draw contour maps or 3D "mountain" plots, and to make animations. We will quickly introduce some of the MATLAB graphics commands that will be most useful in scientific computing. Simple XY graphics We assume that the quantity Y is a function of X, or is related to X in some way. We wish to display a plot that indicates this relationship. If we have an explicit formula, Y = F(X), the appropriate command is FPLOT, as in this example: fplot ( 'x .* sin(x)', [ 0, 10*pi ] ) The formula must be enclosed in single quotes, and the variable is always called X. Figure 1: A Graph Created by FPLOT. MATLAB Syntax: Notice that in the above formula we use "*" to compute 10 * pi, but ". *" to indicate that we want to multiply X by SIN(X).
A second way to carry out an X, Y plot occurs if we have a large set of data pairs (X(1),Y(1)), ..., (X(N),Y(N)). Or 9 x2 + 16 y2 = 144. MATLAB - Documentation. POWER SPECTRAL DENSITY FUNCTION.
