This is my function file:
function ellipseplot(xc,yc,a,b) ((xc^2))/((a^2))+((yc^2))/((b^2)); end
And this is my script file where I call the function:
fplot('ellipseplot(3.5,2.0,8.5,3)',[-20,20]) figure(1)
However, whenever I execute the script file, it throws up a bunch of errors. What am I doing wrong? Thanks.

The errors are as follows:
Error using inlineeval (line 14) Error in inline expression ==> ellipseplot(3.5,2.0,8.5,3) Too many output arguments. Error in inline/feval (line 33) INLINE_OUT_ = inlineeval(INLINE_INPUTS_, INLINE_OBJ_.inputExpr, INLINE_OBJ_.expr); Error in fplot (line 101) x = xmin; y = feval(fun,x,args{4:end}); Error in Functions_1_HW (line 24) fplot('ellipseplot(3.5,2.0,8.5,3)',[-20,20])

I haven't seen the FAQ. Will my code run properly if I follow the instructions on the page?

I'm looking to fix my function so that, when I call it, it will work properly.

Your function does not return anything whatsoever. Nothing. Moreover, it doesn't even do any plots inside of it. It's merely an expression that gets evaluated - that's all. It doesn't get assigned to anything and even if it did, it's not returning anything. Yes, if you follow the FAQ you can get working code.
