Hi,
I have matrix A which has zeros and precipitation values and B which has zeros and probability values. The probability values (nonzero values) in B correspond to the nonzero precipitation values in A. I need to extract values from A, for greater than a probability value from B. Which means look for probability value greater than 0.875 (for example 0.875) from B and get the corresponding values from A.
Can somebody help me in this using matlab.
Thanks in advance.

loc = B > 0.875 ; % Logical index of elements of B greater than 0.875.
val = A(loc) ; % Values of A at locations indexed by loc.
which you can write in one statement
val = A(B > 0.875) ;
