Assuming you have the data in a matrix:
header = ["arm","arm","arm","leg","leg","leg","foot","foot","foot"];
data = rand(3,9);
m=[header;data]
t2 = array2table(data);
for ii = 1:3:length(header)
header(ii) = convertCharsToStrings([char(header(ii)) '_x']);
end
for ii = 2:3:length(header)
header(ii) = convertCharsToStrings([char(header(ii)) '_y']);
end
for ii = 3:3:length(header)
header(ii) = convertCharsToStrings([char(header(ii)) '_z']);
end
t2.Properties.VariableNames = header
