MATLAB: Being equal two matrics contaning NaNs and numbers smaller than 1

matrix

Hi all,
I have two matrics e.g. "a" & "b", which contains some "NaN" elements and numbers less than 1.
a=[NaN 0.4539 0.4532; NaN 0.4536 NaN]; b=[NaN 0.4533 0.4538; NaN 0.4531 NaN];
I want to see if "a" and "b" are equal with NaNs values ? the desired decimal places is 3.
How can I write such program?
thanks in advance,

a=round(a*1000)/1000;
b=round(b*1000)/1000;
a(isnan(a))=0;
b(isnan(b))=0;
test=all(all((a==b)))
% if test =1 then a=b
