Hello,

The nrResourceGrid function was shipped in MATLAB R2020b, and the doc example which you are trying (mentioned above) from the following link here, is the R2021b version. To run the example from the link mentioned above, you need to run in the MATLAB R2021a.

If you want to run the example in MATLAB R2020a, run the example from the MATLAB R2020a doc version from the following link here.

You can open the example from your command window by executing the following command,

openExample('5g/NRChannelEstimationUsingCSIRSExample')
