how to correct this
Error in waveletfssddata (line 42)
Xtrain = cat(2,Xtrain,smat);
Xtrain = [];
scatds_Train = transform(adsTrain,@(x)helperReadSPData(x));
while hasdata(scatds_Train)
smat = read(scatds_Train);
Xtrain = cat(2,Xtrain,smat);
end

Xtrain = cat(2,Xtrain,smat.');
would work, I guess.

smat must always be of size (nx1) in order that you can concatenate Xtrain and smat.' .
Check the size of smat before concatenating in the while-loop.

smat use helperspread function
function x = helperReadSPData(x)
% This function is only for use Wavelet Toolbox examples. It may change or
% be removed in a future release.
N = numel(x);
if N > 8192
x = x(1:8192);
elseif N < 8192
pad = 8192-N;
prepad = floor(pad/2);
postpad = ceil(pad/2);
x = [zeros(prepad,1) ; x ; zeros(postpad,1)];
end
x = x./max(abs(x));
end
this function also give error at
N = numel(x);
then, what can i do;
