Dear Sirs,
I am using the example "Beamforming for MIMO-OFDM Systems" in release R2019b and R2021a
The program gives error in both R2019b and R2021a, the command output is:
'helperGetDesignSpecsParameters' is used in Beamforming for
MIMO-OFDM Systems.
Error in mimo (line 30)
gc = helperGetDesignSpecsParameters();
I went throught the toolbox and I could not find helperGetDesignSpecsParameters.m and helperPlotMIMOEnvironment.m
I wonder why is in the website such a script that does not work,
Thanks in advance, -Enrique-

Hi Enrique Navarro,
Try opening the Beamforming for MIMO – OFDM Systems example using the following command in the command window.
openExample('phased/MIMOBeamformingExample')
The above command will navigate your current working directory to the directory which contains all the necessary files.
You will also see the same command in the Documentation page when you click clicking the View Command button.

Or
(mimo is the script with the example)
openExample('C:\Program Files\MATLAB\R2021a\toolbox\phased\mimo')
Error using matlab.internal.examples.identifyExample (line
19)
Invalid argument "C:\Program
Files\MATLAB\R2021a\toolbox\phased\mimo".
Error in openExample (line 24)
[exampleId, isMainFile] =
matlab.internal.examples.identifyExample(file);
