I'm working on the topic: "Write a function applying the Euler method, approximate function y(x): function [x,y]" but got an error at "Error in Ole2 (line 2)fxy = matlabFunction(f)"
code:
function [x,y] = Ole(f, xfirst, xlast, y0, N)
fxy = matlabFunction(f);
h = (xlast - xfirst)/N;
x = xfirst:h:xlast;
y = x;
y(1) = y0;
for i = 1:N y(i+1) = y(i) + h*fxy(x(i),y(i));
end
end

The reason for the error lies the way you call "Ole", not in the function code that you posted itself.

I predict that you tried to run the code by pressing the green Run button, instead of going to the command line and invoking it passing in appropriate parameters, or having some code in a different file that invokes the function passing in appropriate parameters.
