Can MATLAB 2013b be used to interface with USRP X310? Or do you need higher versions? And how do you actually use the add on package? What is is real purpose? Thanks a lot.

connectedRadios = findsdru;
if strncmp(connectedRadios(1).Status, 'Success', 7)
  switch connectedRadios(1).Platform
    case {'B200','B210'}
      address = connectedRadios(1).SerialNum;
      platform = connectedRadios(1).Platform;
    case {'N200/N210/USRP2'}
      address = connectedRadios(1).IPAddress;
      platform = 'N200/N210/USRP2';
    case {'X300','X310'}
      address = connectedRadios(1).IPAddress;
      platform = connectedRadios(1).Platform;
  end
else
  address = '192.168.10.2';
  platform = 'N200/N210/USRP2';
end

Undefined function or variable 'findsdru'.

No you need r2016b for that. In the below table the appropriate entry is the one under Communications for Embedded Radio.

I also need to know the following: Where do i find a library of commands and inbuilt functions that will be required to configure and use the X310 device from MATLAB?

Thanks a lot.

This link is for E series devices. I need help for X series devices.

Ah, I overlooked that.

According to https://www.mathworks.com/matlabcentral/answers/270423-way-around-to-use-usrp-x310-with-latest-uhd-or-with-uhd-3-8-2-in-matlab-2015b the X310 rev7 is supported (at least with Simulink) as of R2016a

According to https://www.mathworks.com/matlabcentral/answers/278894-the-firmware-build-for-the-usrp-radio-at-192-168-10-2-is-not-compatible-with-the-host-code-build there is a risk with some X3x0 series will not work up to R2015b, and I see from https://www.mathworks.com/matlabcentral/answers/371977-does-matlab-2016a-and-onwards-support-pcie-mxi-connection-with-uhd-3-9-1-and-above that the needed driver appeared in R2016a. There is also a risk that you might be using a newer X3x0 build than that.

If I understand the documentation correctly, the basic software commands are pretty much unchanged since R2012a, but that each MATLAB release works with a different UHD firmware version and copies that firmware into the USRP, so you would need to find out the minimum firmware for the particular hardware build you have, in order to figure out the minimum MATLAB release you need.

So basically i WOULD need MATLAB 2018b version to be as latest as possible for the USRP's of todays market, right?

And again, where will i find a full list of all commands and in built funictions for the USRP? Will installing the support package give me access to them?

thanks

Documentation: https://www.mathworks.com/help/supportpkg/usrpradio/index.html

I am not even close to a specialist on USRP so I do not know what the lastest hardware revs are or when they became supported, but Yes, generally speaking, the latest MATLAB will have the widest support. However, for timing and testing reasons, each MATLAB release does not necessarily support the newest rev that was available as of the MATLAB release date (e.g., mid September 2018 for R2018b.)

Alright, Thanks
