Compute the determinant of an array in Python using the NumPy linear algebra package
ResourceFunction["NumPyDet"][array] computes the determinant of array in Python using the package NumPy. | |
ResourceFunction["NumPyDet"][array,session] uses the specified running ExternalSessionObject session. |
Compute the determinant of a matrix in NumPy:
In[1]:= |
![]() |
In[2]:= |
![]() |
Out[2]= |
![]() |
Or using the built-in Wolfram Language function:
In[3]:= |
![]() |
Out[3]= |
![]() |
Compute the determinant of a real-valued matrix:
In[4]:= |
![]() |
Out[4]= |
![]() |
In[5]:= |
![]() |
Out[5]= |
![]() |
Sparse array:
In[6]:= |
![]() |
Out[6]= |
![]() |
NumericArray object:
In[7]:= |
![]() |
Out[7]= |
![]() |
Complex-valued array:
In[8]:= |
![]() |
Out[8]= |
![]() |
A tensor representing a list of matrices:
In[9]:= |
![]() |
Out[9]= |
![]() |
In[10]:= |
![]() |
Out[10]= |
![]() |
In[11]:= |
![]() |
Out[11]= |
![]() |
Compare with the built-in Det:
In[12]:= |
![]() |
Out[12]= |
![]() |
Make several calls to NumPyDet in the same external session:
In[13]:= |
![]() |
Out[13]= |
![]() |
In[14]:= |
![]() |
Out[14]= |
![]() |
In[15]:= |
![]() |
Out[15]= |
![]() |
End the session:
In[16]:= |
![]() |
For relatively large matrices, the determinant cannot be computed using machine arithmetic:
In[17]:= |
![]() |
In[18]:= |
![]() |
Out[18]= |
![]() |
Use the resource function NumPySignLogDet instead:
In[19]:= |
![]() |
Out[20]= |
![]() |
In[21]:= |
![]() |
Out[21]= |
![]() |
Or the built-in Det:
In[22]:= |
![]() |
Out[22]= |
![]() |
Automatic conversion of the input array to a NumericArray object can fail:
In[23]:= |
![]() |
Out[23]= |
![]() |
In[24]:= |
![]() |
Out[24]= |
![]() |
Convert the array to a NumericArray before passing it to NumPyDet:
In[25]:= |
![]() |
Out[25]= |
![]() |
A call to NumPyDet on an arbitrary precision array fails:
In[26]:= |
![]() |
Out[26]= |
![]() |
In[27]:= |
![]() |
Out[27]= |
![]() |
Convert the array to a NumericArray before passing it to NumPyDet:
In[28]:= |
![]() |
Out[28]= |
![]() |
Or use the machine-precision array:
In[29]:= |
![]() |
Out[29]= |
![]() |
NumPyDet does not issue a warning when precision is lost:
In[30]:= |
![]() |
In[31]:= |
![]() |
Out[31]= |
![]() |
Compare with the built-in Det computed with machine precision:
In[32]:= |
![]() |
Out[32]= |
![]() |
Obtain a more accurate result by computing the determinant with a higher precision using the built-in Det:
In[33]:= |
![]() |
Out[33]= |
![]() |
Verify the result by using still higher precision:
In[34]:= |
![]() |
Out[34]= |
![]() |
