I have an array of 90872x2 double. As follows:
A= B=
1 2
1 2
1 2
1 1
1 1
1 1
1 1
2 1
2 1
2 1
2 1
1 2
1 2
1 2
1 2
1 1
1 1
1 1
2 2
2 2
I want to create a column C with the following values accordinf to the following conditions:
1= when A==1 and B==1;
2= when A==1 and B==2;
3= when A==2 and B==1;
4= when A==2 and B==2;
Therefore I will have:
A= B= C=
1 2 2
1 2 2
1 2 2
1 1 1
1 1 1
1 1 1
1 1 1
2 1 3
2 1 3
2 1 3
2 1 3
1 2 2
1 2 2
1 2 2
1 2 2
1 1 1
1 1 1
1 1 1
2 2 4

C = 1 * (A==1 & B==1) + 2 * (A==1 & B==2) +...
3 * (A==2 & B==1) + 4 * (A==2 & B==2)

C = A ;
C(A ==1 & B == 1) = 1 ;
C(A ==1 & B == 2) = 2 ;
C(A ==2 & B == 1) = 3 ;
C(A ==2 & B == 2) = 4 ;
