Dear All I spent some time in looking for a mistake in my code ; finally I've found that the ACOS of a real vector leads to some complex values (???)
acos(Scar_P(:,1) ./ CM_x_CN(:,1)) (the formula worked so far) I checked that the input values are correct: - Comprised between [-1; 1] using MIN and MAX - Composed only of real values using ISREAL (all the vectors are correct) Thus I do not understand why complex values appear ? May it come from the vectorization ? Paul
