MATLAB: Fprintf applied to variable

fprintf

function balancepoint=findbalpoint(A)
weight=0;
i=1;
while weight<sum(A)/2
      weight=weight+A(i);
      if weight>sum(A)/2
          diff=sum(A)/2-weight;
      end
      i=i+1;
end
note='function assumes constant density'
meter=1/A(i)
string=fprintf('if you subtract %.2f meter from the number %d meter of the bar u get balancepoint', meter, i)
balancepoint=string;
I wonder why the string above is saved as 80 and how you can save the fprintf as ans or as a variablestring
This is what happened when I ran it in matlab:
>> findbalpoint(matrix)
note =
function assumes constant density
meter =
      0.1250
if you subtract 0.13 meter from the number 8 meter of the bar u get balancepoint
string =
      80
ans =
      80

I think you are looking for sprintf and fprintf
