How to insert the data into empty Array?

Hello, Thanks for answering my Q

I have problem as which like the my title.

here is my code.

syms i j

x=[3 4 5]

y=[3 4 -4 6]

A = int16.empty(12,0)

for i=3

      for j=4

           A(j*i)=mod(x(i),y(j))

      end

end

I want to express that each calculated data goes each element in the Array 'A'

How can i handle this..

Thank you all (^오^)
