cbuffer_collinear() bool cbuffer_collinear ( const Cbuffer *  cb1, const Cbuffer *  cb2, const Cbuffer *  cb3, double  ratio  ) Return true if the three values are collinear. Parameters [in] cb1,cb2,cb3 Input values [in] ratio Value in [0,1] representing the duration of the timestamps associated to cb1 and cb2 divided by the duration of the timestamps associated to cb1 and cb3
