I'm trying to prevent extrapolation, the input speed (v) can't be lower than 2 or higher than 200. I'm trying to use if/else but I'm being told by a "test-programme" that "Function does not result in error when input results in extrapolation". What am I doing wrong?
My code:
function c = consumption(v)
load roadster.mat;
x = 2:2:200;
y = consumption_Whpkm;
xx=2:200;
pp=spline(x,y);
c = ppval(pp, v);
if v<2 | v>200
error ('Too fast/slow')
else
contine
end
end

Don't answer your own question, and just with a comment. Use a comment. Or edit your question.
Moved an answer by Rava into a comment.
"Should I use try/catch? If so, how would that work? I'm very new to programming and Matlab, any help is appriciated."

I am guessing that v is non-scalar, in which case you will need to use any:
if any(v<2 | v>200)

I wonder if the else branch of that if may fail, when the "contine" function is executed. Is that a miss-spelling of "continue"?

I quite like the sound of "contine", whatever it may do. It sounds like a french holiday.
