How can I just display a sentence with words and values in my function using only a string and without the values showing again?

 function A = Area_of_a_circle()
          r = input('Enter radius: ');
          A = 2*pi*r^2;
          s = ['The area of a circle with radius ',num2str(r),' is ', num2str(A)'.'];
       disp(s)
  end

seems to me your function does just that

you can check out fprintf though

it does but it also show below the sentence the value of A like A = 45.25474

You need a comma after num2str(A)

[Gracious Ngonga]

yet i want it just to end at the sentence alone

I don't get this issue over here.

maybe you didn't put a semicolon ; after calling Area_of_a_circle?

A = Area_of_a_circle()

gives this output:

The area of a circle with radius 10 is 628.3185.

A =

628.3185

but if you add a semicolon

A = Area_of_a_circle();

you get the output you wanted

Also, like walter mentioned you need a comma or space after the num2str to get the last period like that matlab transposes A twice instead of concatenating the period
