fcnstr=input('Put Desired Function: dy/dx=', 's') ; f=inline(fcnstr) ;

    x0=input('x(0)=') ;
    y0=input('y(0)=') ;
    xf=input('x(f)=') ;
    n=2 ;              
    h=(xf-x0)/n        
%~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    format long g
    xa(1)=x0 ;
    ya(1)=y0 ;
for i=1:n
xa(i+1)=xa(i)+h ;      
k1 = h*f(xa(i),ya(i));
gives error:
"??? Error using ==> inline.subsref at 17

Too many inputs to inline function.

Error in ==> FODESu4oRKv1 at 43

k1 = h*f(xa(i),ya(i));"

Hi Pramit

I have an understanding that you want to make use of the inline function in your code; but you are not able to and it is giving an error "Too many inputs to inline function".

You need to specify the variables (and the order of the variables) explicitly when you use inline().

See the bottom example in the reference page:
