I have a matrix A which holds the positions, which further i want to add from matrix B.
for example :
A=[1 2 5]
B=[ 0 0 9 0 10
0 0 9 0 10
9 9 0 9 9
0 0 9 0 10
10 10 10 10 0]
from B's first row i want to add 1st 2nd and [4] 5th elements the answer will be 0+0+10
A matrix represents the position to be added in B

C=sum(B(1,A));
Open the online doc and under "Getting Started" read tutorial info on Array Indexing. I recommend working thru this introductory info in sequence to get going in Matlab quickly...
