fprintf applied to variable

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
