Thread Subject:

Matlab "stand alone" DLL and C#

Hello!

Here is what I want to do.
I would like to create a simple function and then build a stand alone
library.

Then I would like to call this function from C# (.net 2.0).

DLL must be stand-alone, so I don't need to do any installation on
client computer. (if any installation is required, it should be
silent --> without any user interaction)

Best regards,
Damjan

Hi,
you can use the MATLAB Compiler (or MATLAB builder for .NET)
http://www.mathworks.com/products/compiler
http://www.mathworks.com/products/netbuilder/

but you will always need to install the MCR (think of it as the run-time
environment for MATLAB) on the client machine (this needs to be
done only once, see the chapter of "Deploying Applications" in the
online help following the links above).

Hi Damjan,

You can call *any* exported Win32 DLL entry point from C# using
P/Invoke (Platform Invoke), so that isn't a problem.

I'm guessing that you want to create your simple function using the
MATLAB m script? If so, you'll need the MATLAB Compiler to compile
that into a DLL. To run, you'll be required to install the MATLAB
Compiler Runtime (MCR) on the target. I believe it can execute
silently.

Good luck.

Hey John,

Thanks for your answer.

I found a recorded webinar that explains deploying Matlab
applications.

.Net builder was mentioned in the tutorial. Of course I have to check
it out. After a while I was able to make .net assembly and include it
(as a reference) into my C# project (VS2005).

Here are my sample files:

% mySum.m
function [result] = mySum(a, b)
    result = a + b;
end

// C# - Windows Application
private void button1_Click(object sender, EventArgs e)
{
    try
    {
       // TypeInitializationException: The type initializer throw
exception
        Operationsclass o = new Operationsclass(); // <--
Exception thrown here
        o.mySum(1, 2);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

After some blind clicking, I found checkbox to include MCR (Matlab
Runtime Component). Then I built a package (150MB).
After installing a package my C# App seems to work fine.
(Haven't checked yet on target computer -> without matlab
installed).

Is this the solution?
1. Make .NET Assembly
2. Include MCR into package
3. Silently install MCR
4. Install C# Application
5. Run Application

Damjan

Hello!

All problems solved!
Thanks a lot guys.

There is only one thing left.
I need to find a way to include MCRinstaller into VS2005 Setup
project or some switches to silently install MCR.

Damjan
