the following test is failing
%!assert (isnan (sqrtm ([0 1; 0 0])))
but it is not clear to me, what is the expected results
as isnan applied to a matrix produces a matrix
> sqrtm ([0 1; 0 0])
warning: sqrtm: matrix is singular, may not have a square root
ans =
0 NaN
0 NaN
> isnan(sqrtm ([0 1; 0 0]))
warning: sqrtm: matrix is singular, may not have a square root
ans =
0 1
0 1
