Load .mat (Matlab) file on run time (.exe)

[GPC]

Hello, 

I would like to make an application capable of reading 2 variables from a Mat file, both are double precision arrays and I know their names.

I have searched a lot on the Internet, both at ni and mathworks web sites, and I ended up with two problems:

• Must be a solution that will work on any Windows machine (Matlab may not be installed);
• Must be able to read big arrays (10.000 items at least).

I have attached the file. The array on the file has 300.000 elemenst but reading just the first/last 10.000 will be ok.

Does anyone knows how to do this?

Thank you verry much!

Hi GPC,

You can try the MATLAB@ DataPlugin.

MATLAB® is a registered trademark of The MathWorks, Inc.

You could also use the mat-file io library, which is written in pure G and supports every data type that MATLAB supports.  There should be no problem building an executable using the library.  If you do decide to use this library, wait till the latest version is uploaded later today.  There are a couple changes that will make it easier to use.

I had no problem opening your mat file using the library:
