Hi
I have a Dataset padded with -500 so the row length of the matrix stays the same. Now I want to extract an array from a row containing only the values that aren't -500.
e.g
A = [2,1,2,3,4,-500,-500,-500 ; 2,3,4,5,-500,-500,-500,-500]
i've tried this but it gives me only the boolean answer
A1 = A(1,:) > -500 -> A1 = [1,1,1,1,1,0,0,0]
what i want would be A1 = [2,1,2,3,4]
Can anybody help me?
Thanks in Advance

You can use the logical vector to index the main array i.e
A(A1)
