If the data is stored in a cell array as shown in your image, then:
cumsum(cell2mat(B))
here B is the cell array of data.
If it is a vector then simply:
cumsum(B)
where B is the vector of data.

What are the contents of m? Is it the same set of values as the commulativeSum in the screenshot above?
If so, then try:
cumulativeSumMat = cumsum(cell2mat(m));
If the result has to be a cell array, then add the line:
cumulativeSum = num2cell(cumulativeSumMat);
