textscan - import the k-th out of n columns and ingore the 1st row which contains column names

My txt file contains more than 100 columns and rows. How can I save any column avoiding the following

Mydata = textscan(fid,'%f %f %f %f %f ... %f','HeaderLines',1);  %   %f as many as the number of columns

If any line/function is more efficient for my case please recommend it.

Thank you in advance.

cols_to_keep = [17, 83:85];   %for example
fmt = repmat({'%*f'}, 1, NumberOfColumns);  %read but do not sae
fmt(cols_to_keep) = {'%f'};    %read and save
fmt = [fmt{:}];
MyData = textscan(fid, fmt, 'HeaderLines', 1);
