Hi,
I have a table where one column contains words like 'Clear', ' Clouds' and 'Rain'.
I want to replace those for values like 1,2 and 3.
Anyone who can help me with this?

% Assume the column has the data
x.omst=["Clouds"; "Rain"; "Clear"]
x = struct with fields:
omst: [3×1 string]
% You can use the categorical data
x.omst = categorical(x.omst);
disp(x.omst)
Clouds Rain Clear
% Or numbers
x.omst = double(categorical(x.omst));
disp(x.omst)
2 3 1
