Generate the Ulam matrix
ResourceFunction["UlamMatrix"][n] returns the n×n Ulam matrix. |
A 5×5 Ulam matrix:
In[1]:= | ![]() |
Out[1]= | ![]() |
Visualize a large Ulam matrix:
In[2]:= | ![]() |
Out[2]= | ![]() |
Show the same matrix mod 7:
In[3]:= | ![]() |
Out[3]= | ![]() |
By default, an exact matrix is computed:
In[4]:= | ![]() |
Out[4]= | ![]() |
Use machine precision:
In[5]:= | ![]() |
Out[5]= | ![]() |
Use arbitrary precision:
In[6]:= | ![]() |
Out[6]= | ![]() |
Mark the positions of prime numbers in the Ulam matrix and visualize the result:
In[7]:= | ![]() |
Out[7]= | ![]() |
Color numbers in the Ulam matrix by the number of their divisors:
In[8]:= | ![]() |
Out[8]= | ![]() |
