Subtracting previous cell?

I have a multidimensional variable SC (1x1x104) which is storage capacity for a region from 2004 to 2012. I want to subtract current cell values from previous values so I can get a whole new variable TSC. I tried using the for loop code below but it didn't give the desired result. I hope someone can help with this. Thanks!

for t=1:length(SC); TSC=SC-(SC(:,:,t)-1)./t; end

[KSSV]

TSC = cell(1,103) ;
for i = 1:103
    TSC{i} = SC{1,1,i}-SC{1,1,i+1} ;
end

Hi, I ran the code and got this error message,

Cell contents reference from a non-cell array object. Is there something I ought to have done?

@Dorcas Oluwabimpe Idowu: your question clearly states that you have cells of a cell array, and so KSSV's answer gives you a solution for cell arrays. But apparently actually you don't have a cell array at all, probably you have a numeric array. Please show us the output of this command:

whos SC

I'm sorry about the mix up in my question. Actually, what I want to achieve is to solve this equation;

TSC=SC(t)-SC(t-1)/change in t.

The SC file is a multidimensional matrix with lat, lon and time dimensions.

I have attached the output of the command in my previous question to this question.
