My goal is to replace any elements in array A that are either NaN or <0 with the corresponding elements in Array B. Below is my code: A = [1, 2.1, -5, 6, -3, 8, NaN]; B = [8, 8.2, 8, 8, 8, 8, 8]; C = replace!(x -> (x<0 || isnan(x)) ? B : x, A) Here is the error: MethodError: Cannot `convert` a…

[image] leon: Why isn’t it working? Possibly because x iterates over the scalar elements of A and that code tries to replace such elements by full B arrays. A comprehension could be used: C = [a < 0 || isnan(a) ? b : a for (a,b) in zip(A,B)]
