Hello everyone. I am currently a senior engineering student and quite new to the program. I have created an excel file (4x90) with column headings of Mach, "a", velocity, and RPM. I would like to have a user specify a certain Mach number, and then have LabVIEW interpolate out a value for "a" and RPM for this Mach number. I assume this function is done with the array commands in Labview, but not sure exactly where to start. Thanks for the help
