Hi,

Let A be your array.

idx = A>360 ;
A(idx) = A(idx)-360 ;
idx = A<360 ;
A(idx) = A(idx)+360 ;

something is wrong, I applied it getting no error but no changes applied on my array

[KSSV]

Before and after applying check the values with indices idx.

 A = (A - 360) .* (A > 360) + (A + 360) .* (A < 0) + A .* ((A >= 0) & (A <= 360));
