在 MATLAB Online 中打开

Note that the data are overlaping in each segment as per the requirements

1st cell 1% of data
2nd Cell 10% of data
3rd Cell  20% of data
.....

If data are non overlaping case,it can be easiliy achieved using mat2cell.

One Attempt: Do modify accordingly

data=randi(100,[200,353]);
[r,c]=size(data);
r=1:round(r/10):r;
c=1:round(c/10):c;
data_seg=cells(1,8);%80 for 8 
for i=1:length(1:8)
    data_seg{i}=data(1:r(i),1:c(i));
end 
data_seg
