Hello Nathaniel Porter,

As per my understanding, you want to obtain specific values from a PDF file. Such that values are between 48 and 64 in a specific column and want to retrieve the corresponding values in the column to the right.

You can follow the steps given below for the same:

% Split the text into lines 
lines = splitlines(str); 
% Initialize variables 
result = []; 
% Iterate over the lines 
for i = 1:numel(lines) 
    line = lines{i}; 
    
    % Use regular expressions to find values between 48 and 64 in the third column 
    pattern = '\d+\s+\d+\s+([48-64])\s+(\d+)'; 
    match = regexp(line, pattern, 'tokens'); 
    
    % If a match is found, extract the values 
    if ~isempty(match) 
        value = str2double(match{1}{1}); 
        correspondingValue = str2double(match{1}{2}); 
        
        % Store the values in the result 
        result = [result; value, correspondingValue]; 
    end 
end 
% Display the result 
disp(result);
