For example, we have the following variables stored:

Altitude = 2000

Mach=0.7

And suppose the script created an output file called output.txt.

Is there a way to, at the end of the run, rename the output.txt file to be called Output2000ft0.7m.txt so that it doesn't get overwritten on the next run?

在 MATLAB Online 中打开

Altitude = 2000;
Mach = 0.7;
old_file_name = 'output.txt';
new_file_name = sprintf('Output%gft%gm.txt',Altitude,Mach);
movefile(old_file_name,new_file_name)
