I have the following code which is supposed to write out to a .env file.
function write_env(profile_name, depth_and_sound_speed, num_source, source_depth,num_reciever, reciever_depth, freq)
%Function to turn data into a .env file:
% profile_name -- name of the file written out
% depth_and_sound_speed --sorted matrix of increasing depth and
% respective sound speed
% freq -- source frequency
%
depth_bottom = max(depth_and_sound_speed(:,1))
avg_ssp = mean(depth_and_sound_speed(:,1))
depth_and_sound_speed = num2str(depth_and_sound_speed)
copy = zeros(size(depth_and_sound_speed,1), 3);
for i = 1:size(copy,1)
copy(i, :) = [num2str(depth_and_sound_speed(i,1)) num2str(depth_and_sound_speed(i,2)) '/'];
end
header = sprintf(['''' profile_name ''' \t ! TITLE\n' ]);
header = sprintf([header, num2str(freq,'%d') '\t! FREQ (HZ)\n']);
header = sprintf([header, num2str(1) '\t ! NMEDIA\n']);
header = sprintf([header,'''SVF''' '\t !SSPOPT (Analytic or C-linear interpolation)\n']);
header = sprintf([header, num2str(51) ' ' num2str(0) ' ' num2str(depth_bottom), '\t! DEPTH of bottom (m)\n']);
footer = sprintf(['''A''0 \n']);
footer = sprintf([footer, num2str(depth_bottom) ' ' num2str(avg_ssp) ' ' num2str(0) ' ' num2str(1) '\t/\n']);
footer = sprintf([footer, num2str(1) '\t ! NSD \n']) %number of source depth
footer = sprintf([footer, num2str(1000) '/ \t !SD(1:NSD) (m) \n' ])
footer = sprintf([footer, num2str(51) '/t !NRD \n'])
footer = sprintf([footer, num2str(0) ' ' num2str(5000) '/ \t ! RD(1:NRD) (m) \n'])
footer = sprintf([footer, num2str(1000) '\t ! NR \n'])
%footer = sprintf([footer, num2str(])])
fid = fopen(profile_name, 'w');
%insert / at the end of the
fprintf(fid, header);
dlmwrite(profile_name, depth_and_sound_speed, '-append', 'delimiter', ' ', 'precision', 3)
dlmwrite(profile_name, footer, '-append', 'delimiter', ' ', 'precision', 3)
fclose(fid);
end
The footer array keeps having spaces between characters. Is there any way to remove this?
I would like to get it into this format:
You can test out the script with the following inputs:
a = [5 6; 2 3; 4 6; 2 5; 6 7; 2 3]
write_env('A.env', a, 1, 1000 , 51, 0, 1600)

Answer is to change the ' ' to '' in the footer write.
Before:
dlmwrite(profile_name, footer, '-append', 'delimiter', ' ', 'precision', 3)
After:
dlmwrite(profile_name, footer, '-append', 'delimiter', '', 'precision', 3)
