How can i set the empty elements in the above picture to zero, i have tried T = cellfun('isempty', Z),
but it does not recognize the cells as empty.
Anyone got ideas of how to do this?

It's impossible for us to know from a screenshot what type of data you have. Assuming it's a cell array, it's also impossible for us to know if the cells are actually empty.
It's much better if you attach your data as a mat file. Screenshots are useless.

Please attach the file, so that we can try on it.

Following assumptions are made for the solution stated below:
- The csv file is being read as a matrix and some cells are actually empty.
- The name of the file is 'file1.csv'
- When the file is read as the matrix, the empty cells are automatically recognized as 'NaN'.
The code for the question, keeping the above assumptions is:
A = readmatrix('file1.csv');
dim = size(A);
for i = 1:dim(1)
for j = 1:dim(2)
if isnan(A(i,j))
A(i,j) = 0;
end
end
end
disp(A)

The loops are not needed, you can simply use the line below:
A(isnan(A))=0;
