I have found the multiple codes for PSK signal but they plot the consulation diagram, which contain binary values but when i plot them it gives me error.

Did you convert binary values to decimal values? To convert binary values into decimal values bin2dec() can be employed.

I have generated that 32psk .mat file which i have uploded, But i don't know its correct or not.
function y = psk32Modulator(x,sps)
%psk8Modulator 32-PSK modulator with pulse shaping
% Y = psk8Modulator(X,SPS) 32-PSK modulates the input X, and returns the
% root-raised cosine pulse shaped signal Y. X must be a column vector
% of values in the set [0 7]. The root-raised cosine filter has a
% roll-off factor of 0.35 and spans four symbols. The output signal
% Y has unit power.
persistent filterCoeffs
if isempty(filterCoeffs)
filterCoeffs = rcosdesign(0.35, 4, sps);
end
% Modulate
syms = pskmod(x,32);
% Pulse shape
y = filter(filterCoeffs, 1, upsample(syms,sps));
end
