questions on assigning values from a vector

Hi all,
I am trying to do this assignment:
x1=x(1);
x2=x(2);
.
.
xN=x(N);
How could I do it using a for loop so that I don't need to write them down explicitly. Thanks.

x = randn(10,1);
for nn = 1:10
eval(['x' int2str(nn),' = x(nn);']);
end
But eval() is pretty inefficient, so are you sure you want to do this. Anyway, you'll see that if you execute the above you will have variables x1, x2, ... x10 in your workspace

This is generally recommended against as it is much easier (not to mention faster) to manipulate a 1xn vector x than dealing with n scalar arrays.
