[Scilab-users] acos leads to complex values

[Carrico, Paul]

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
