National Instruments LabView software has a native file format called LabView Measurement File (LVM, extension .lvm). This m-file, lvm_import.m, reads LVM files and imports the data into the MATLAB workspace.

LVM is an ascii text file format, and the data can be imported into MATLAB using the built-in import.m function. However, import.m has some limitations: it cannot handle multi-part LVM files, and it does not return the contents of the file and section headers. lvm_import.m handles all types of LVM files, and returns specific information such as date, time, data column names, etc.
