Undefined function 'euler' for input arguments of type 'function_handle'.

Why does the program say "Undefined function 'euler' for input arguments of type 'function_handle'. " to this code?

function dydx = funct(x)

dydx = 4/(1+x^2);

end

function euler(func,y0,h,x0,xf)

x=linspace (x0,xf,h)

y=(y0)

for k=1:(length(x)-1)

    y(k+1) = y(k)+h*func(x(k));

end

y=y'

x=x'

plot (x,y)

xlabel ('x')

ylabel ('y')

end

When in the Comand Window I type: euler(@funct,0,20,0,1)

• download the attached files and save in your working directory
• Now execute euler(@funct,0,20,0,1) from your command window
