Compute the Cholesky decomposition of an array in Python using the NumPy linear algebra package
ResourceFunction["NumPyCholeskyDecomposition"][array] computes the Cholesky decomposition of an array in Python using the package NumPy. | |
ResourceFunction["NumPyCholeskyDecomposition"][array,session] uses the specified running ExternalSessionObject session. |
Compute the Cholesky decomposition of a symmetric positive-definite matrix in NumPy:
In[1]:= |
|
In[2]:= |
|
Out[2]= |
|
In[3]:= |
|
Out[3]= |
|
The original matrix:
In[4]:= |
|
Out[4]= |
|
In contrast, CholeskyDecomposition always returns an upper-triangular matrix:
In[5]:= |
|
Out[5]= |
|
In[6]:= |
|
Out[6]= |
|
Compute the Cholesky decomposition of a real-valued matrix:
In[7]:= |
|
Out[7]= |
|
In[8]:= |
|
Out[8]= |
|
In[9]:= |
|
Out[9]= |
|
In[10]:= |
|
Out[10]= |
|
Complex matrix:
In[11]:= |
|
Out[11]= |
|
In[12]:= |
|
Out[12]= |
|
In[13]:= |
|
Out[13]= |
|
In[14]:= |
|
Out[14]= |
|
Sparse array:
In[15]:= |
|
Out[15]= |
|
In[16]:= |
|
Out[16]= |
|
In[17]:= |
|
Out[17]= |
|
NumericArray object:
In[18]:= |
|
Out[18]= |
|
A tensor representing a list of matrices:
In[19]:= |
|
Out[19]= |
|
In[20]:= |
|
Out[20]= |
|
In[21]:= |
|
Out[21]= |
|
Make several calls to NumPyCholeskyDecomposition in the same external session:
In[22]:= |
|
Out[22]= |
|
In[23]:= |
|
Out[23]= |
|
In[24]:= |
|
Out[24]= |
|
End the session:
In[25]:= |
|
NumPyCholeskyDecomposition returns a Failure object if the input matrix is not positive definite:
In[26]:= |
|
Out[26]= |
|
In[27]:= |
|
Out[27]= |
|
