The following code prints a vector of uninitialized entries.<br>
<br>
ierr = VecCreate(comm,&v);CHKERRQ(ierr);<br>
ierr = VecSetSizes(v,n,n);CHKERRQ(ierr);<br>
ierr = VecSetType(v,VECSEQCUSP);CHKERRQ(ierr);<br>
ierr = VecView(v,PETSC_NULL);CHKERRQ(ierr);<br>
<br>
In contrast, if the type is VECSEQ the vector is initialized to zero. So it seems that VecSet(v,0.0) must always be called. Is this the expected behaviour?</blockquote><div><br></div><div>There is no guarantee of initialization for any Vec type.</div>
