Multiplication of matrix element of different size matrix

I want to perform this

m(l,j)= sum of (i=1 to M)(x(i,l)*w(i,j))/ sum(i=1 to M)x(i,l)

where ,x will get from this code

v=[1 0;0 1;1 0]
rowperms = perms(1:size(v, 1));
x= cellfun(@(rowperm) v(rowperm, :), num2cell(rowperms, 2), 'UniformOutput', false);

w is 3*5 matrix. How to perform it? what I have done is

for l1=1:ll
    for j1=1:jj

summ1=0.0;
sumx1=0.0;
        for i1=1:ii
            m1(l1,j1)= (x(i1,l1))*(w(i1,j1))%total load of cell l induced by part j(for a fixed value of l and j and differerent value of i multiplying x and w)
            summ1=summ1+m1(l1,j1)

              x1(i1,l1)= x(i1,l1)% no of machine in cell l
              sumx1=sumx1+x1(i1,l1)

          end
              m(l1,j1)=summ1/sumx1% avarege cell load

      end
  end
