Hi,
Given the following matix
D=[1 2 3 4 5 6 7 8] A(1:length(D),1:10) = 110 S= [0 0 8 0 0 8 0 0; 0 0 0 5 0 0 0 0];
I want to add the value different from 0 in S, to a specif location in A.
A = 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110
In particular, the value 8 must be added in the 6th column of A, while the value 5 must be added to the second column of A.
To understand in which raw to allocate the element, it depend on the position in S.
1) In this case the first 8 is in position (1,3) so must be allocated in A(3,6): 3 because it's in position 3 and 6 because all the values different from zero of the first raw of S must be added in the 6th column of A
2) The second 8 is in position (1,6) so must be allocated in A(6,6)
3) The first 5 is in position S(2,4) so must be allocated in A(4,2): 4 because it's in position 4 and 2 because all the values different from zero of the 2 raw of S must be added in the 2th column of A
Finally i want to obtain
A = 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 118 110 110 110 110 110 115 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 110 118 110 110 110 110 110 110 110 110 110 110 110 110 110 110
