1. Some simple operations are possible on vectors .

                                                                                                                      
         VBIAS     : Y(i) = a + X(i)                                                                                       
         VSCALE    : Y(i) = a * X(i)                                                                                       
         VADD      : Z(i) = X(i) + Y(i)                                                                                    
         VMULTIPLY : Z(i) = Z(i) * Y(i)                                                                                    
         VSUBSTRACT: Z(i) = X(i) - Y(i)                                                                                    
         VDIVIDE   : Z(i) = X(i) / Y(i)                                                                                    
   

   In these operations the resulting vectors are created automatically. Note that for operations with mathematical functions like SQRT or trigonometric functions etc... , SIGMA must be used (we will see examples later).
