I want to create a function named result() that I can use to print to the screen:

 fprintf('\n*** Summary Data for Scenario:\n')
 fprintf('%30s%12d\t%s\n', 'Runway Length:', runway, 'ft');
 fprintf('%30s%12.1f\t%s\n', 'Rotation Speed:', rotate, 'knots');

where 'runway' and 'rotate' are user inputs from the rest of my code.

I tried:

 function result()
     fprintf('\n*** Summary Data for Scenario:\n')
     fprintf('%30s%12d\t%s\n', 'Runway Length:', runway, 'ft');
     fprintf('%30s%12.1f\t%s\n', 'Rotation Speed:', rotate, 'knots');
 end

I want this in my code because the full result() function is (or would be) about 6 lines long and will be used multiple times.

@William Edwards: what exactly is your question? What are you trying to do? The function that you show us does not output any variables, so it is not clear what relation the title has to the body of your question.

在 MATLAB Online 中打开

function result(runway, rotate)
     fprintf('\n*** Summary Data for Scenario:\n')
     fprintf('%30s%12d\t%s\n', 'Runway Length:', runway, 'ft');
     fprintf('%30s%12.1f\t%s\n', 'Rotation Speed:', rotate, 'knots');
 end
