Note that your function is ill-defined for x == 0, since it passes all three conditions. You should use strict comparison, < instead of <=.

I'm not sure what you mean by solve. The roots of that function is obviously just 0.

How to write functions and how to use if statement is covered in the Getting Started tutorial in the doc and in million of other tutorials.
function s = mysignum(x)
if x > 0
s = 1;
elseif x < 0
s = -1;
else
s = 0;
end
end
