Using 'single' arrays with the "filter" command

We have to minimize our application's memory footprint and execution time, so I'm trying to move from "double" data arrays to "single" data arrays. The problem is that the "filter" command appears to return "double" filter states. Is there a way to use "single" data with the filter or even the "conv" command?

Make sure all your inputs to filter are singles.
Here's an example for a simple moving average:
x = rand(100,1,'single');
a = ones(1,10,'single')/single(10);
b = single(1);
xf = filter(a,b,x);
class(x)
