Now I am new to matlab, and now the basic syntax, however I am not sure how to write a function to loop for instance the following recurrence equation:
$y(n+1)=\exp(-y(n))$
..
where $y(1) = \exp(-y(0))$
and $y(0) = x$

First define $x$:
x = 1;
Next, define the vector $y$:
n = 10;
y = zeros(n,1);
Initialize the vector:
y(1) = x;
Then build a loop:
for i = 2:n
y(i) = exp(-y(i-1));
end
To plot:
plot(1:n,y)

Thank you! And if I would plit it? I would at plot(y(i)) – Gauss Dec 03 '15 at 02:34

@Gauss Type plot((1:n),y) – mzp Dec 03 '15 at 02:43

Hm it gives an error when it hits y(0) – Gauss Dec 03 '15 at 12:43

@Gauss I fixed it, the "for" needs to start at $i=2$. – mzp Dec 03 '15 at 13:25

It works¡ uhh however if I want to plot it I am getting dots instead of a line, any idea how to fix that, – Gauss Dec 03 '15 at 14:04

@Gauss I just run the exact code I wrote and got a line. I don't know what could be going wrong.. – mzp Dec 03 '15 at 14:07

Hm I have put the plot() in for, and getting three point while the vector has more point – Gauss Dec 03 '15 at 14:10
