NumericZeroQ
​
NumericZeroQ[a]
returns True if every entry of
a
is zero within tolerance
-8
10
after Chop.
​
​
NumericZeroQ[a,tol]
uses the supplied tolerance tol.

Basic Examples  
(1)
Zero matrix is reported as True:
In[1]:=
NumericZeroQ
[{{0.,0.},{0.,0.}}]
Out[1]=
True
A matrix with entries smaller than the default tolerance is also True:
In[2]:=
NumericZeroQ
[{{1*^-10,0.},{0.,1*^-12}}]
Out[2]=
False
A clearly non-zero matrix is False:
In[3]:=
NumericZeroQ
[{{0.,0.5},{0.,0.}}]
Out[3]=
False
