clc
clear all
close all
a=0;
b=2;
y=5;
x=1/2;
f3=inline('1/(sqrt(x^2+y^2)');
[f6]=eval(f2)
??? Undefined function or method 'eval' for input arguments of type 'inline'.

@adem ski: why on earth are you using outdated and almost obsolete inline?
The very start of the inline documentation states
Why are you ignoring the advice of the MATLAB documentation? Your task would be trivial with an anonymous function, do you have a good reason why you cannot use one?
Why on earth do you want to use awful, anti-pattern eval?

"i want use eval"
Why? It's the one function that beginners should never use.
