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.

Below is my partial code based on your suggestion. Unfortunately, the result shows the same result with a different dimension. Please correct my misunderstanding.Tq.

    commulativeSum{i}=cumsum(m{i})

[Aniruddha Katre]

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);
