If you have source. you can do it with below.

data = [2 7 3 50 5 6 60]
catdata = categorical(data)
catidx = double(catdata)
sdata = sort(data)
converted = sdata(catidx)

If there is no source, how to convert it?

catdata = categorical([2 7 3 50 5 6 60])
converted = str2num(char(catdata))'

If useful, thumb up!

Read about double

Data=[2 36; 56 23]; %If i execute this data it will be in double format
To_categorical=categorical(Data)
idx = double(To_categorical) ;
Data(idx)

This works only when there is still "Data=[2 36; 56 23];" in the workspace.

Please check the file with this attachment. I just want to convert that categorical table to double format.

catdata = categorical([2 7 3 50 5 6 60]);
catnames = categories(catdata);

converted = str2double(catnames(catdata)).'

converted = 1x7

2 7 3 50 5 6 60
