take rows from one matrix and put in output matrix

I am trying take the values from matrix a and place them in Matrix B as the rules are iterated. % a value of 1 reperesnts a car in the cell and 0 represents %and empty space% a=zeros(2,100); newa=zeros(2,100);

g=1; max=100; a(1,50)=1; a(2,30)=1; B(1,:);(2,:)=a; B=a;

while (g<max), for i=2:99 if a(ij+1)==0, newa(ij+1)=1 else newa(ij)=0;

end end g=g+1; a=newa; b=newb; B(g,:)=a;

end spy(B),

Don't override max() (use it as your own local variable) - it's a built-in function.

If B and A are the same number of rows

B(:, columnNumberB) = A(:, ColumnNumberA);

This replaces the entire column "columnNumberB" in array B with what's in "columNumberA" of array A.

I don't know what "as the rules are iterated" means
