I have a cell array A. and marrix B
A = [2,4,0.5,0.34;0.01,4,0.5,0.34;10,4,0.2,0.6;10,4,0.2,0.6;19,15,0.7,0.6]
B = [1,1;1,2;2,4;2,3;3,4;3,3;4,1;4,2;5,2;5,3]
I am trying to use the indices in matrix B, to index into Matrix A and return the values
C =
2 4
0.34 0.5
0.6 0.2
10 4
15 0.7
I then wish to add the values across columns and return a vector D
i then wish to take each row element in C and divide it by its row total in D, and return the values in a matrix E
E =
2./6 4./6
0.34./0.54 0.5/0.54
0.6./0.8 0.2./0.8 ETC ETC
I have made a start but clear a look is the worng thing to do here in order to extract the values from A using the indcies in B. All help appreciated. Would cellfun work?
rowcolidx = B
rowcolidx=zeros(1,size(B,1));
for i = 1:size(B(1:end,:),1)
temp = A(rowcolidx(i,1),rowcolidx(i,2));
ReturnsVal = temp;
end
