NullSpace
 Usage
Notes
 Further Examples
Here is a nonsingular matrix.
In[1]:=
|
Out[1]=
|
That is, the null space of the nonsingular matrix mm is trivial. There is no nonzero vector v such that mm.v = 0.
In[2]:=
|
Out[2]=
|
Here the null space has dimension  .
In[3]:=
|
Out[3]=
|
This checks the result.
In[4]:=
|
Out[4]=
|
These two vectors span the null space of the  matrix m2x4.
In[5]:=
|
Out[5]=
|
Multiplying m2x4 by any linear combination of the vectors v1 and v2 gives the zero vector.
In[6]:=
|
Out[6]=
|
This simplifies the expression.
In[7]:=
|
Out[7]=
|
The rank of the matrix is the difference between the dimension of the range and the dimension of the null space.
In[8]:=
|
Out[8]=
|
In[9]:=
|
Using NullSpace to Find a Linear Recurrence This defines the function findLinearRecurrence which gives a linear recurrence corresponding to the list of numeric quantities vals.
In[10]:=
|
This finds the linear recurrence corresponding to the first few values of the Fibonacci sequence.
In[11]:=
|
Out[11]=
|
This finds the linear recurrence corresponding to a random sequence of complex numbers.
In[12]:=
|
Out[12]=
|
In[13]:=
|
Out[13]=
