How do I put variable values into a text string in MATLAB?

Question

I\'m trying to write a simple function that takes two inputs, x and y, and passes these to three other simple functions that add, multiply, and divide

Answer 1

You can use fprintf/sprintf with familiar C syntax. Maybe something like:

fprintf('x = %d, y = %d \n x+y=%d \n x*y=%d \n x/y=%f\n', x,y,d,e,f)

---

reading your comment, this is how you use your functions from the main program:

x = 2;
y = 2;
[d e f] = answer(x,y);
fprintf('%d + %d = %d\n', x,y,d)
fprintf('%d * %d = %d\n', x,y,e)
fprintf('%d / %d = %f\n', x,y,f)

Also for the answer() function, you can assign the output values to a vector instead of three distinct variables:

function result=answer(x,y)
result(1)=addxy(x,y);
result(2)=mxy(x,y);
result(3)=dxy(x,y);

and call it simply as:

out = answer(x,y);
