I’m not certain what you want, so I’ll venture this:
x=[3,7,2,9,4];
product_x = prod(x)
elements_x = length(x)
elements_x = numel(x)
produces:
product_x =
1512
elements_x =
5
elements_x =
5

If m is your matrix:
theProduct = prod(m(:)); % Multiply all elements together.
theCount = numel(m); % Count the number of elements in the array.
