MATLAB: Assign Ranking in Matlab

cellsrankingrowssort

I have several cell-type variables A{Y,1}(Z x 13 cells) all sorted by column C. I need to assign a ranking (add column R) for the corresponding sorting order.
Example for a B {Y,1} (8 x 3 cells). My original cell is:
A B C
MJ 65 0
MJ 321 0,0125
MJ 2 0,0125
MJ 1987 0,0125
MJ 87 0,02
MJ 5 0,0375
MJ 743 0,0375
MJ 124 0,05
I would like to rank (column R) each A{Y,1} cell-type, considering that in case of tie, the mean value should be assigned.
A B C R
MJ 65 0 1
MJ 321 0,0125 3 %Assign mean value

MJ 2 0,0125 3
MJ 1987 0,0125 >> 3
MJ 87 0,02 5
MJ 5 0,0375 6,5 %Assign mean value
MJ 743 0,0375 6,5
MJ 124 0,05 8
Thanks for your help.

v={'MJ' 65 0
'MJ' 321 0.0125
'MJ' 2 0.0125
'MJ' 1987 0.0125
'MJ' 87 0.02
'MJ' 5 0.0375
'MJ' 743 0.0375
'MJ' 124 0.05}
[a,b,c]=unique([v{:,3}])
d=accumarray(c,(1:numel(c))',[],@mean)
v(:,4)=num2cell(d(c))
