Im having an issue with this matlab assignment and i get get this one string to work

Here is the code:

% Load satellite data

url = 'https://celestrak.org/NORAD/elements/gp.php?GROUP=geo&FORMAT=tle';

sat_data = webread(url);

sat_data = splitlines(sat_data);

num_sats = numel(sat_data)/3;

% Ask user for search criteria

search_string = input('Enter search string: ', 's');

min_inc = input('Enter minimum inclination: ');

% Loop through each satellite and check if it meets the search criteria

num_matching_sats = 0;

for i = 1:num_sats

name = char(sat_data(3*(i-1)+1));

inc = str2double(char(sat_data(3*(i-1)+3)).(9:16));

if startsWith(name, search_string, 'IgnoreCase', true) && inc >= min_inc

num_matching_sats = num_matching_sats + 1;

fprintf('%d %.2f %s ', num_matching_sats, inc, name);

end

end

% Print number of matching satellites

fprintf('%d Satellites found ', num_matching_sats);

Here is the error im getting

here is whats suppose to come out of the program

>> Sat_Finder_name_inc_Solution Enter search string: Enter minimum inclination: 45
