This will give you the number of zeros in particular rows and columns:
M = [105 0 55 15; 15 0 25 75; 55 0 0 10; 0 0 5 0];
[zr,zc] = find(M == 0);
Z = accumarray([zr zc], 1 )
rowzeros = sum(Z,2)
colzeros = sum(Z,1)
produces:
rowzeros =
1
1
2
3
colzeros =
1 4 1 1

If you want the row and the colum with the maximum of values equal to zeros, I propose (for a 2D matrix) :
[numberOfZeroCol,colWithMaxZero] = max(sum(array == 0, 1))
[numberOfZeroRow,rowWithMaxZero] = max(sum(array == 0, 2))
but I'm not sure that's what you want.
