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.

在 MATLAB Online 中打开

 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) ;
