prevent function from displaying output

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 ?

What exactly do you want to stop? Your question is very unclear... Probably you want to remove the

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

line, if you don't want this to display your functions...

Answer 1

[Razvan]

f = delet;

please try the following. my mistake i uploaded a bad example:

function [f] = delet();

f1 = @(x) x^2 + 3;

f2 = @(x) x^2 + 3;

f = @(x) f1(x(1))+f2(x(2));

once called : f = delet;

f =

    @(x)f1(x(1))+f2(x(2))

[Razvan]

you have to put semicolon in the body of the function too:

f = @(x) f1(x(1))+f2(x(2));

Answer 2

[Wayne King]

Put a semicolon after delet when you call the function

 f = delet;

[pemfir]

please try the following. my mistake i uploaded a bad example:

function [f] = delet();

f1 = @(x) x^2 + 3;

f2 = @(x) x^2 + 3;

f = @(x) f1(x(1))+f2(x(2));

once called : f = delet;

f =

    @(x)f1(x(1))+f2(x(2))

[Daniel Shub]

Are you trying to evaluate the function? Do you want f()?

[pemfir]

i will use it in fsolve

Changes, like the previous comments suggest, using a semi-colon, should stop output form appearing on your terminal.

Also you want to explore 'str2func()' as a way to build function handles.
