Hello everyone,<br><br>I am wondering what function in petsc computes
the pointwise product of two vectors. For example, vin1=[1,2],
vin2=[3,4]; I need a function to output vout= vin1.*vin2 = [3,8]. I can
write my own function, but I am worrying whether the vin1 and vin2 are
known by all the processors (I guess not if they are parallel vectors
and distributed). More precisely, when one processor computes vout[i] =
vin1[i]*vin2[i], is it possible that vin1[i] or vin2[i] are not known
by this particular processor and the program output an NaN or other
meaningless vout[i]? Thank you very much!<br>
