MAT-File IO Library for LabVIEW

I am using both, LabVIEW and MATLAB to develop a software application. How can I read/write a .mat file in LabVIEW?

You have two alternatives to use .mat files in LabVIEW:

1. You could use the MATLAB® DataPlugin, After installing the dataplugin, you can use the LabVIEW Data Storage VIs to manipulate .mat files. Refer to Introduction to LabVIEW Data Storage VIs for more details.

2. Another option is the MAT-File IO Library for LabVIEW, this is a third-party library not supported directly by National Instruments and distributed throught the VI Package Manager. After installing the library you can refer to the examples available in C:\Program Files (x86)\National Instruments\LabVIEW XXXX\examples\matio (XXXX,is your LabVIEW version)
