Display Variable Value In a String

Hello guys,

I have a prbolem and i don't know how to solve it.

X=214 is a vriable

command={
    'NACA X'
    ''
    'OPER'
    'VISC ON'
    'RE'
    '160000'
    };

      id = fopen('command.dat', 'w+');                                         
      fprintf(id, '%s\n', comandi{:});
      fclose(id);

I have to write the variable command into a .dat file. However my variable X is a number that is into a for cycle and changes his value. With this syntax in the file i will find 'NACA X' but what i need is to find 'NACA 214' for example.

Can someone help me?

Thanks very much

Try this:

X = 214;
command = {sprintf('NACA %d',X)  '' 'OPER' 'VISC ON' 'RE' '160000' };
