I need help on how to save this as a .dat file. When I do

save bloodinfo.dat 

and then do

type bloodinfo 

it is not there.

How can I save this file?

.dat is not a standardized file format.

Are you looking to save it as a text file, a csv file except with a .dat extension?

What datatype are you working with?

[per isakson]

Your example looks like the content of a text file. Is it? Inside Matlab this "info" may be stored in a cell array or maybe a table. How is it stored?

"do save bloodinfo.dat" Exactly how did you do that?

Try this

fid = fopen('bloodinfo.dat', 'wt');
for k = 1 : length(value1)
    fprintf(fid, '%s, %s, %d, %d\n', patientName{k}, bloodtype{k}, value1(k), value2(k))
end
fclose(fid);
type('bloodinfo.dat');

Obviously replace the variables with whatever your variables are named.
