## Derived from col2num
%% Test simple case
%! assert (col2num ("a"), 1, 1e-16);

%% Test case insensitivity
%! assert (col2num ("A"), 1, 1e-16);

%% Test more complicated string
assert (col2num ("ydf"), 17010, 1e-16);

%% Again, test case insensitivity
assert (col2num ("Ydf"), 17010, 1e-16);
assert (col2num ("yDf"), 17010, 1e-16);
assert (col2num ("ydF"), 17010, 1e-16);
assert (col2num ("YDf"), 17010, 1e-16);
assert (col2num ("yDF"), 17010, 1e-16);
assert (col2num ("YdF"), 17010, 1e-16);
assert (col2num ("YDF"), 17010, 1e-16);
