using .mat as a control in LABVIEW

[Abul Hasan]

Hi everyone

I am interested to use .mat data as  a control in my LABVIEW program.

As a simple program, if I display control value on any indicator I use only one control and one indicator. Now I am interested that control value would be the same value as it is on .mat data stored any directory.

Thanks

Best Regards

Are you referring to Matlab .mat files, or something else? There is no "control" for .mat files. There are controls to display data, but you have to read the data yourself in code and write that data to an indicator. You could create an XControl if you really wanted to.

.mat is matlab in the form of an array (say 3 rows,2col). Rather than to input this mat data through a keyboard, I want to call the name of variable in the control. Actually, in my case I have to change the value of control many times based on the mat data.

So from what I understand, you want to import the variables from the Matlab workspace to LabVIEW, rather than a .mat file which would consist of Matlab script.....

Is that correct?

[Abul Hasan]

Yes this correct.
Is there any solution?

Did you refer to Mathscript node ?

Unless there is application requirement where your matlab workspace variable values are changing dynamically with LabVIEW running in parallel, mathscript node will work.

Else, you can use ActiveX call for Matlab and poll the workspace variables in matlab.
