Error using cat Dimensions of arrays being concatenated are not consistent.

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

Answer 1

[Torsten]

Xtrain = cat(2,Xtrain,smat.');

would work, I guess.

having same error again

Error using cat

Dimensions of arrays being concatenated are not consistent.

Error in waveletfssddata (line 43)

Xtrain = cat(2,Xtrain,smat.');

[Torsten]

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.

[Rimsha Muzaffar]

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;
