Circshift applied to columns by different amounts

Hi everyone:

I have a large matrix in the form:

a1 =
[1 1 1 1;
1 1 1 NaN;
1 1 NaN NaN;
1 NaN NaN NaN];

and I need to have it each column shift down by the number of NaNs in
that column yielding:

a1New =
[1 NaN NaN NaN;
1 1 NaN NaN;
1 1 1 NaN;
1 1 1 1];

Is there an efficient way to do this?

Cheers,

t.
