回答： triztyme 2016-4-23

I have the following code that I want it to print "Air density = x.xx kg/m^3" and "Blade radius = x.xx cm." Is it possible to add the 'kg/m^3' and 'cm' so it prints after the user entered numbers or should I be using a different input prompt?

density = input('Air density = ');

radius = input('Blade radius = ');

Try using fprintf with \b (backspace) to "remove" the newline

 density = input('Air density = ');
 fprintf('\b kg/m^3\n');
 radius = input('Blade radius = ');
 fprintf('\b cm\n');

I have not seen any terminal since the ADM3A on which backspace removed a newline.

So here's what I ended up doing:

 density = input('Enter air density in kg/m^3: ');
 fprintf(outputfile,'Air density  = %5.3f kg/m^3',density);
 radius = input('Enter blade radius in cm:  ');
 fprintf(outputfile,'\nBlade radius = %2i cm',radius);

thanks for taking a look
