write a script to write another new .dat

I have to write a script which can write the data to a new .dat file. I already have a vector = [2000 3000 4000 7000 11000; 300 293 275 246 200], and I save as a.dat

Here we I got

load a.dat
time = a(1,:);
temp = a(2,:);
plot (time,temp,'k--')

now, I have to write an another .dat maintain different number of vector, and I have to write it on the script that i have(which is above script) and name it by b.dat.

What do you want to save in the second file?

 save('b.mat', 'variablename');

will do the job.

another like vector = [2000 3000 4000 7000 11000; 300 293 275 246 200] for example vector = [1 2 3 4 5; 100 200 300 400 500] save as b.dat however, i have to write it in one script without open another one.

Simply add to the existing script (or write a separate function and call it from the first script).

that's what I asking for, I don't know which code should I use
