Extract Values from Matrix row

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)

Better yet, combine them into 1 line,

A1 = A(1,A(1,:)~=-500)
