mata
A = (1,2,3\4,5,6)
C = J(2,3,.)
for (i=1; i<=2; i++) {
C[i,.] = A[i,.]
C[i,.] // display
}
end

I tried to make a simple modification to this so that each element in
the matrix was assigned in nested -for- loops rather than assigning a
row at a time.

mata
A = (1,2,3\4,5,6)
C = J(2,3,.)
for (i=1; i<=2; i++) {
for (j=1, j<=3, j++) {
C[i,j] = A[i,j]
}
}
C
end


But this generates the error:
unexpected end of line
--------------------------------------------
r(3000);

end of do-file
r(3000);


The nested loop works fine in other simple examples such as

mata
C = J(2,3,.)
for (i = 1; i<=rows(C);i++) {
for (j = 1; j<=cols(C);j++) {
C[i,j] = i+j
}
}
C
end

But not when I make the element by element assignment C[i,j] = A[i,j]
above.

Thanks for your consideration,
