select all from matrix where column less than value

Is there a way in MATLAB to select from a matrix with a range of values in column A(:,1) where:

B = select from A where A(:,1)<20070000

Cannot find this logic anywhere

EDIT: I need to select these indicated rows from all columns of A.

A straightforward solution looks like this:

rowInds = find(A(:,1)<2007000);
B = A(rowInds,:);

This will have the same number of columns as A. As Dan said it works without the find, using just the logical array to specify the rows directly. Either way is fine.

The question has been clarified to requiring all columns, so the above is sufficient.

Actually to get all the rows can just do this:

B = A(A(:,1)<20070000,:)
