I have a table with column names A, B C. I want to create an array col_index=[1 0 1] by using the column names only.

Ran in:
A = zeros(3,1); B=rand(3,1); C=ones(3,1);
T = table(A, B, C)
T = 3×3 table
A B C _ ________ _ 0 0.10002 1 0 0.034853 1 0 0.06117 1
VarNames = {'A', 'C'};
col_index = ismember(T.Properties.VariableNames, VarNames)
col_index = 1×3 logical array
1 0 1
