Hello everyone,

I have a doubt about FFT function on Matlab. I know when I have an even and real function its FFT give only real values. But, when I calculate, for  example, the FFT of a cosine function result real and imaginary values. I think I making a mistake on my interpretation of this result. Anyone can help me please :)

Thanks and sorry for my english!!!
