for to parfor loop,and for with logical indexing to parfor loop

Hi, I have got two doubts:

-> the first one is to change this for loop to parfor loop, I have done all, but due to the last sentence I cannot use the parfor loop:

ORGINAL LOOP:

   for n=1:fbaseDatosAct
               [vehDel(1),vehDel(2),vehDel(3)]=vehDelanteMia(baseDatosAct,n,t); 
              [baseDatosAct(n,columnaV),estaParado]=reduceVelocidad(t,baseDatosAct(n,:),vmin,vehDel,pasoTemp); 
  end

PARFOR LOOP:

 parfor n=1:fbaseDatosAct
             veDelanteMiaTemp=zeros(1,3);%variable estatica para la paralelizacion
             baseDatosRow = baseDatosAct(n,:);%variable estatica para la paralelizacion
             veDelanteMiaTemp=vehDelanteMia(baseDatosAct,n,t);
            [baseDatosRow(1),estaParado]=reduceVelocidad(t,baseDatosRow,vmin,veDelanteMiaTemp,pasoTemp);
            baseDatosAct(n,:) =baseDatosRow;<-HERE TROUBLE WITH PARFOR!!
 end

->My second doubt with parfor is if I could convert a for loop which contents a logical indexing to parfor one, for example the original for loop would be the next code, where bDActual and bDAnterior are matrix of nx8.

         for n=1:1:fbDActual
             indice=find(bDAnterior(:,columnaID)==bDActual(n,columnaID));
             if(~isempty(indice))
                 if((bDAnterior(indice,columnaInc)~=0) && (bDActual(n,columnaInc)==0))
                     bDActual(n,columnaV)=bDActual(n,columnaV)+incrVel;
                     if(bDActual(n,columnaV)>vMax)
                         bDActual(n,columnaV)=vMax;
                     end
                 end
             end
         end
