I have a Table in MATLAB, suppose the table is A of dimensions 21392x1970. There are 1970 columns in table A, as evident. There is a column named "Temperature" and I would like to find out the column number of that column eg. between 1-1970 which value in my table. How can I find the column number of a MATLAB table column by specifying the name of the column? Any help in this regard would be highly appreciated. Cheers and Thanks!

tidx = find(string(T.Properties.VariableNames) == "Temperature")

Would
find(strcmp(T.Properties.VariableNames,'Temperature'))
also work?

Yeah, strcmp, and ismember would both work. I've been using the datatype string strings for pretty much everything so doing an equal (or ismember) is more natural.

varnames = A.Properties.VariableNames;
[tf, column_number] = ismember('Temperature', varnames);
if ~tf
error('Temperature is not one of the table variables')
end
