Change string words to number in table

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
