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
