a=0
b=2
y=5
x=1/2
f1=inline('(1+x^2)/(sqrt(x)+3)')
f2=inline('(1+x^2)/(sqrt(x)+3)')
f3=inline('(1+x^2)/(sqrt(x)+3)')
f4=inline('(1+x^2)/(sqrt(x)+3)')
f1=feval(f1,x)
f2=feval(f2,a,b,x)
f3=feval(f3,x,y)
f4=feval(f4,a,x,b,y)
i see this problem
??? Error using ==> inline.feval at 26
Too many inputs to inline function.
Too many inputs to inline function.
Error in ==> Untitled3 at 10
f2=feval(f2,a,b,x)
how can i fix it

f1=f1(x)
f2=f2(x)
f3=f3(x)
f4=f4(x)
But inline will be removed in a future release. Use Anonymous Functions instead:
x=1/2;
f1=@(x) (1+x^2)/(sqrt(x)+3);
f1value=f1(x)

When you use inline() [which should be only if you have a need to prove that you can use inline], then you should define all of the variables you expect to use in the function, and their order.
a=0
a = 0
b=2
b = 2
y=5
y = 5
x=1/2
x = 0.5000
f1=inline('(1+x^2)/(sqrt(x)+3)', 'x')
f1 = Inline function: f1(x) = (1+x^2)/(sqrt(x)+3)
f2=inline('(1+x^2)/(sqrt(x)+3)', 'a', 'b', 'x')
f2 = Inline function: f2(a,b,x) = (1+x^2)/(sqrt(x)+3)
f3=inline('(1+x^2)/(sqrt(x)+3)', 'x', 'y')
f3 = Inline function: f3(x,y) = (1+x^2)/(sqrt(x)+3)
f4=inline('(1+x^2)/(sqrt(x)+3)', 'a', 'x', 'b', 'y')
f4 = Inline function: f4(a,x,b,y) = (1+x^2)/(sqrt(x)+3)
f1=feval(f1,x)
f1 = 0.3372
f2=feval(f2,a,b,x)
f2 = 0.3372
f3=feval(f3,x,y)
f3 = 0.3372
f4=feval(f4,a,x,b,y)
f4 = 0.3372
