Index exceeds the number of array elements (11)

Hi, how could i take it off the error?

[Ruben Lange]

Hello,

It seems that you tried to use entry 11 of your vector x. In line 4 however, you stated that x would be a vector of length 10 with values ranging from 0 to 1. In your for loop you let i cycle from 1 to 20, so as soon as i reaches 11, it can't find a value in x as x only reaches to 10 entries.

Hope that helps.

Thanks!

I have another mistake but a don't know what it meens

You need explicit multiplication between the 2 and the x.

Also as we discuss in your other posting, you need to use exp()

fplot('-exp(-x)+x.^2-2*x+2',[0 1])
