xlim and ylim
I want to compute the maximum and minimum values in both x-axis and y-axis of my image (xmin, xmax, ymin and ymax)? I know that I should use xlim and ylim but I don't know how to use them to get these values from my image? ... 20 May 2010 21:35

control object: uitable
Hi guys There are many items in the uitable. Some of them have been handled. Some of them need to be handled. I want to changed the background color of these handled items so that they can be distinguished from those not handled. Thanks in advance Zhong ... 20 May 2010 19:24

Fixed-point matrix inversion
Hello, I have implemented a relatively simple Kalman filter within an embedded Matlab block in Simulink. I have tested my model and now I am ready to convert it to fixed point for subsequent code generation and execution on an ARM7-based embedded system. However, I am running into an issue with the matrix inversio... 20 May 2010 18:18

problem building mex on Windows (fortran and c++)
Hi, I want to build the Pardiso matlab interface on a Win 64 computer, with Intel Fortran and Visual Studio. Building the interface is rather complicated and the instruction only are for Linux. Unfortunately I'm don't know a lot about creating mex files except very simple ones, where you only have to supply the ... 20 May 2010 19:24

Is there a way to have matlab through an error if a constant such as pi is reassigned?
Hi All, I just spent several hours tracking down a code bug caused by the value pi being used as a variable. Is there a way to have matlab through an error if a constant such as pi is reassigned? Thanks, Craig ... 20 May 2010 18:18

dynamic figures -- too much
Hi all, I am trying to prepare a number of figures for a publication. Most/all of them are less than straightforward in terms of the matlab graphics commands needed. E.g. * boxplots with complex labels and grouped in a non-trivial way, * subplots with overall and individual x/y-axis labels, * line plots where ... 20 May 2010 18:18

Counting crossings of a threshold
Hello, I'm currently using MATLAB to analyse some accelerometer and EMG data of the press-up cycle for various press-up stances, e.g. wide, preferred, narrow. I am currently having an issue trying to determine how many press ups have been done from the graph (I know its 4, and I can see its 4, I just need to writ... 21 May 2010 04:04

Rewriting equality or inequality constrains for fmincon or quadprog

Dear All, I wanted to ask the following question. If I have a quadratic optimization problem of the type min(x) x' Q x Where Q is symmetric but indefinite (3x3) matrix, and x is column vector of length 3. Fmincon and quadprog could solve this.

Executing Matlab code using Visual basic
I used to do the same. GUI in VB and math in Matlab. I found that the best way (for me) is compiling matlab routines into .dll and use it with a program written in VB. Advantage is simple: you do not have to have Matlab installed on the client computer and run-time engine files freely distributed. Disadvantage (not r... 20 May 2010 16:06
