What does ./ mean in matlab?

I am porting code from Matlab to Java. And being entirely unfamiliar with Matlab I am not sure what this "./" operator means in Matlab. Found in this function generated in matlab neural network code.

if true
%code
% Sigmoid Symmetric Transfer Function
function a = tansig_apply(n)
a = 2 ./ (1 + exp(-2*n)) - 1;
end

end

look at redivide().

From MATLAB HELP: x = A./B divides each element of A by the corresponding element of B. Inputs A and B must have the same size unless one is a scalar value. A scalar value is expanded into an array of the same size as the other input.
