Creating DLL in Matlab and using them in Matlab?

Hi,

is it possible to create dll in Matlab and then using it in other Matlab
apllication?

I've made a simple function and put it into dll. But when I try to use this
library in other apllication written in matlab it doesn't works.

Any idea?

hi e-shresk,

I once created a matlab dll, and called it in c code. it worked. 

I guess you have to check whether you dll was built correctly or not.

ps. why don't u call matlab function directly?

Hmmm. 

The function is very simple:
==========================
function var_o = testlib(var_i)
if var_i == '1',
    var_o = 'jest';
else
    var_o = 'brak';
end
==========================

Compilation: mcc -W lib:xlib -T link:lib testlib

After it, I have *.dll *.lib *.h

Tryin' to load library:

loadlibrary('xlib.dll','xlib.h');

The result is:

Warning: Warnings messages were produced while parsing.  Check the
functions you
intend to use for correctness.  Warning text can be viewed using:
[notfound,warnings]=loadlibrary(...) 
> In loadlibrary at 394

Where is the problem?

> ps. why don't u call matlab function directly?

I have a pack of functions that I wouldlike to use with few different
matlab compiled programs.

One way is to write a s-function and then use the .mexw32 file.

slow optimization using nonlcon with GA within matlab toolbox and mixed integer problem using GA within Matlab
greeting all, i'm using nonlcon(nonlinear inequality constraint) with GA from the toolbox provided by matlab. does anyone notice the extreme slowlness in evaluating nonlinear constraint as compared to other linear constraint? my problem for nonlinear constraint is as follow c(1)=x+y^2-2*ones(N,1) where x and y are Nx1 vector. which means if N increases, the size of constraint increases. and to clarify, the min problem is sometime like min c'z where z=[x;y], which means x and y are some range of variable within z(just a matter of problem formulation) well, is there anyone with other alternative or is it possible or method in including non-linear constraint directly to fitness function? (well, actually nonlcon deals nonlinear constraint by using Augmented Lagrangian Pattern Search from what i see from the help file, or am i wrong?) and one more question, is there anyone that attempt to attempt to apply mixed integer problem into the GA in matlab? For now, i can only switch before pure integer or pure real number problem, but not mixed at the moment. I will be trying to add in some repair operator to fix up the variable that needs to be integer and other remaining in real number. I'm not sure why you are using ga to solve your problem. Did you find fmincon unsatisfactory in any way?

Problem using matlab created dll when <Library>Initialize() is in code
Hi all, I am running into a problem which can be best descrivbed as below: I have a C++ program which calls a matlab created library (compiled with MSVC2008). I am using Qt Creator as IDE and the program is being compiled with MSVC2008 as well. I followed all the instructions regarding the dll compilation and how to integrate it to my code (MCR installation, etc.). I then set up my project file this way: 1. an includepath to the folder where the .lib, .dll, .h have been created D:/C++ Offline/Matlab/ 2. an includepath to .../MATLAB Compiler Runtime/v714/extern/include 3. I link the following libraries D:/C++ Offline/Matlab/Test_Matlab.lib (the library I created) C:/Program Files/MATLAB/MATLAB Compiler Runtime/v714/extern/lib/win32/microsoft/mclmcrrt.lib 4. I added also #include "Test_Matlab.h" Here is the problem: When I compile the application and when calling mclInitializeApplication(NULL, 0) everyhing works ok (including the connection to matlab as the boolean returned evaluates to true) AS LONG AS Test_MatlabInitialize() is NOT in the code (even if it is not called at startup). However as soon as I add in the code Test_MatlabInitialize() (even if not called) I get the following error: Stopped in thread 0 by: Exception at 0x1cdb4a, code 0xc0000005: write access violation at: 0x8, flags=0x0 What I don't understand is that it seems to be able to compile bu not to run the program (crashes immediately) even if the function Tes...

What is the best way to import Excel files, with stock data, into Matlab? I’m using Matlab R2010b (64-bit)
What is the best way to import Excel files, with stock data, into Matlab? I’m using Matlab R2010b (64-bit) I’m trying to import historical prices of stock data. Matlab keeps cutting off the header of each column; it gives me only values. I am thinking that this is a data-type-mixing-issue, or whatever it’s called. I have ‘Dates’ in ColumnA, and ‘MSFT’, ‘PWER’, ‘KO’, and ‘SBUX’, in ColumnB-ColumnE. Basically, if I put the Excel file in my Matlab folder and double-click the file, I see the values in a matrix (no dates and no headers), I hit ‘Next’. Then, I see only one option; one radio button is enabled – ‘Create variable matching preview’. The other two options, ‘Create vectors from each column using column names’ and ‘Create vectors from each row using row names’ – both are greyed out. I’ve seen videos, on YouTube and on the Matlab site, where people import excel data and these options are NOT greyed out. No matter what I do, there options are ALWAYS greyed out. The problem is, when I click ‘Finish’ in my ‘Workspace’ I have a variable named ‘data’ all values in a 575x4 matrix, but I have NO DATES and I have NO HEADERS on the columns. All of this seems to go into another variable, called ‘textdata’; all dates and headers ate in textdata. This is VERY inconvenient. I’m trying to analyze some stock data and I have no headers, so I have no idea which stock is which (I can figure it out, but I think Matlab should do this for me). Also, I have no dates corresponding to ...

Using vsgDesktop to create Gabor in Matlab
I'm trying to use the Cambridge Research Systems vsgDesktop toolbox to display a Gabor patch on a second monitor. Specifically, I want to display a sequence of Gabor patches with various contrasts. As far as I've tried, the crsDrawGabor() command does not accommodate this - it displays a Gabor, for which you can alter the size of the Gabor, but that's it. I can't change the contrast, spatial frequency, or anything else using this command. So what I want to do is to use vsgDesktop to display a sequence of Gabor patches, for which I can alter their spatial frequency and contrast settings (0% to 100%). Can anyone help me on this? Jeremy, I just came across your post and don't know if you are still interested in obtaining help with this, but I recommend using the CRS MATLAB Toolbox for the VSG. It is easy to interface to and is a free download for registered VSG systems.
