MATLAB: How do you assign the output of an anonymous function to a variable

How do I assign the output of an anonymous function to a variable so that I can manipulate the output?

Best Answer

Just like with any other function call. For example,

f = @(x) x.^2 + sin(x);
myVariable = f(17.2);    %assign output to variable.

MATLAB: Unwanted variable can I not assign

If you don't want every answer from function just type "~" instead of variable.

Example:

[~,a2]=size(x)

MATLAB: Assign an input to an anonymous function

I did it like this...

function []=test
syms x
digits(9);
func= input('Please enter f(x) = ');
Xest= input('Pleae enter an initial guess = ');
d=diff(func,x);
x=Xest;
for i = 0:15
    ds=eval(d);
    fs=eval(func);
    x = x-((fs)./(ds));
    vpa(x)
    if x(i-1)==x(i)
        break
    end
end
end

Didn't end up using anonymous function.

The if loop is a little messed up beacuse I'm trying to find a way to break it once the answer repeats but I basically just changed x from symbolic and assigned the value of the guess to it then evaluated the function using "eval()"

I'm sure there's a better way to do it.
