i want to create a 2 dim matrix which creates 1000 rows vs 1000 columns which will look like a table, if the prime number occur output 1 in the cell and if not prime output 0

Create 2 dim matrix 0 --> 999 rows, 0 --> 999

columns Prime_matrix = zeros(1000,1000);

For i= 0 --> 1000000

If I is == prime number

X = i % 1000

Y = i / 1000

I think this does what you want. I used 100 numbers in a 10x10 array to illustrate. Just change N to 1000.

N = 10;
Prime_matrix = reshape(isprime(0:N^2-1),N,N)'

Prime_matrix = 10×10 logical array
   0   0   1   1   0   1   0   1   0   0
   0   1   0   1   0   0   0   1   0   1
   0   0   0   1   0   0   0   0   0   1
   0   1   0   0   0   0   0   1   0   0
   0   1   0   1   0   0   0   1   0   0
   0   0   0   1   0   0   0   0   0   1
   0   1   0   0   0   0   0   1   0   0
   0   1   0   1   0   0   0   0   0   1
   0   0   0   1   0   0   0   0   0   1
   0   0   0   0   0   0   0   1   0   0
