[ublas] memory allocation in local function

Hi,

I'm a ublas newbie and have a basic question about memory allocation
with ublas. Is it valid to assign a matrix in a local function and then
use it in other functions, or do I have to use pointers?

Here is a short example.

class X
{
        int sizex, sizey;
        void init();
        ublas::matrix<double> mat1;
}

X::X()
{
        sizex=3;
        sizey=4;
}

void X::init()
{
        mat1 = ublas::matrix<double>(sizex,sizey);
}

void X::useMatrix()
{
        std::cout << mat1;
}

Is mat1 always defined after calling init() ?

thx in advance
