matlab function inside while loop

I've created this small program just for simplicity of the question, I am having some trouble using my function inside a while loop

this is the script;

x = 1;
y = 1;
while x<10
    y = func(x,y);
    x = x + 1;

this is the function, func;

function [] = func(x,y)

y- exp(-x)

end

I get the error of 

Error using func
Too many output arguments.

what am I doing wrong

When you declare the function:

function [] = func(x,y)

You have specified that there will be no return values, yet when you call it you require a return value:

y = func(x,y);

To fix this issue you must alter your function declaration, e.g.:

function y_out = func(x,y)

Also, within your function declaration you have y- exp(-x), which will not change the value of y; did you intend to have y=exp(-x)?
