the rows represents the thicknesses and columns represents wells (boreholes).

assuming thicknesses h1, h2, h3, and h4 in first row in thicknesses matrix

then the depths sholuld be z1= h1, z2 = h1+h2, z3 = h1+h2+h3, and z4 = h1+h2+h3+h4 in first row in depth matrix

thanks in advance

% a random 10-by-4 matrix of thicknesses
% each element between 1 and 15:
h = randi(15,10,4)
h = 10×4
  15    13    11
  10     9     5
   3     1     5

% depth is cumulative sum along rows of h:
z = cumsum(h,2)
