Error in polarcodeparameters (line 10)

encoder = comm.PolarEncoder(N,K);

I do not find any reference to functions with those names, not anywhere.

The 5G Toolbox has nrPolarEncoder and nrPolarDecoder, but not comm.PolarEncoder or comm.PolarDecoder .

The names suggest something in the Communications Systms toolbox, but I find no evidence that functions with those names ever existed.

https://www.mathworks.com/matlabcentral/fileexchange/13553-data-encoding-ami-nrz-rz-polar-bipolar-manchester might maybe be useful as a replacement.

Unrecognized function or variable 'nrPolarEncoder'.

% still not working

[Walter Roberson]

nrPolarEncoder needs the 5G toolbox

[Ali Al raeesi]

i already downloaded the 5G toolbox and it sitll not working

is there somthin i must do

[Walter Roberson]

Sorry I had the name slightly wrong
