Problem creating MATLAB driver

I'm able to communicate with my Rigol and Keithley instruments using SCPI commands in MATLAB R2022b.

When I try to create a MATLAB driver for my Rigol instruments, using for example:

makemid('rgds4k') 

I get an error message: The specified driver could not be loaded.

Here is a link to the Rigol IVI drives website. In this example, the IVI driver name rgds4k is for the DS4000 scope.

However, makemid('kedmm6500') for my Keithley DMM6500 works fine.

When I use the ividriverlist command, ALL of my instruments are listed along with the corresponding IVI-C driver names.

I'm assuming that a MATLAB driver must be created before trying to use ividev? as follows:

dev = ividev("IviScope","myScope","IDQuery",true,"ResetDevice",true)

since I get the following error message: Vendor Driver Error 0xBFFA000B: The path name is invalid.

I've downloaded and installed all of the latest IVI-C drivers from the Rigol website, but I get the same error message when trying to create a MATLAB driver for any of them. I also get a Warning: makemid will be removed in a future release. There is no simple replacement for this.

Any ideas on how to resolve these issue?

Hi Donald,

You can list the available IVI drivers (more specifically IVI-C drivers) on your machine by looking at the output of

>> Iviinfo = instrhwinfo('ivi')
>> Iviinfo.Modules

You can call MAKEMID on the modules listed in the output of the second command.
