Hi everyone,
I have a table (T) that contains data and have extracted column data from it as follows:
data_1_forward = T.foward_wheels + 435;
data_1_backwards = T.backwards_wheels + 435;
data_1_left = T.left_wheels + 435;
I want to put this in a loop since it is repeated code but unsure on how to do this with strings in the index. I also want the loop to output data_1_foward, data_1_backwards... as separate arrays or vectors.
Many thanks

numvars = width(T);
data_1 = cell(numvars,1);
for K = 1 : numvars
data_1{K} = T{:,K};
end
Now, data_1 is a cell array with one entry for each variable.
I also want the loop to output data_1_foward, data_1_backwards... as separate arrays or vectors.
You might want to consider
numvars = width(T);
vars = T.Properties.VariableNames;
data_1 = struct();
for K = 1 : numvars
thisvar = vars{K};
data_1.(thisvar) = T.(thisvar);
end
This would create a struct named data_1 that has one field for each variable in the table.
