MATLAB: Argument list of a function handel

function handleMATLABpass list as function argument

I can pass the elements of a list to a function handle:

>> f=@(x,y)x+y

>> f(1,2)

ans = 3

>> x=[1 2]

>> f(x(1),x(2))

ans = 3

But how can I pass the list to the function handle instead of explicitly specifying each element of it? I tried the following but neither worked:

>> f(x)

??? Input argument "y" is undefined.

>> f(x(:))

??? Input argument "y" is undefined.

Thanks for help!

xcell = num2cell(x);
f(xcell{:});

Note that if you are not using scalars, the approach would need to be modified.

You have to call your function as:

x = 42;
y = fun(x);

Simply using the ‘Run’ option by clicking the green arrow in the Editor will not work.

x0=[1,1];
xcell = num2cell(x0);
f(xcell{:}) = some_value;
