MATLAB: Prevent function from displaying output

Question

I have the following function (please do not suggest that i change the function itself):

function [sumf] = delet();

for i = 1:2;

syms d u ;

f = (char(vpa(subs((d/u – strcat('k',num2str(i))),{d,u},{1,2}))));

a = symvar(char(vpa(f)));

f = ['@(', sprintf('%k1,', a{1:end-1}), a{end}, ') ',f];

f = eval(f);

x = strcat('f',num2str(i));

eval(sprintf('%s = f',x));

end

sumf = @(k) f1(k(1))+f2(k(2));

once called : f = delet; f = delet;

f =

0.5 – 1.0*k1

f1 =

    @(k1)0.5-1.0*k1

f =

0.5 – 1.0*k2

f2 =

    @(k2)0.5-1.0*k2

on the display. how do i stop this ?

Answer 1

f = delet;
