How to sort and save data in same workspace / excel?
显示 更早的评论
I have problem to save the data that i already sort by it Loading Port and Length. Im using for loop, the data that save in the final workpace is only the last sorted category, not the whole data.
data = readtable('Dummy.xlsx');
% LOADING
[Lport, a, LOADING] = unique(data(:,7));
LP = max(LOADING);
for G = 1 : LP
fprintf('\n\n\n\t\t\t\t\t\t\t\t\t <strong>LOADING PORT %d </strong>\n', G)
L = data(LOADING==G,:);
% display(data(LOADING==G,:))
[Length, b, LENGTH] = unique(L(:,3));
l = max(LENGTH);
for G = 1 : l
fprintf('\t\t\t\t\t\t\t\t\t<strong>LENGTH : Category %d</strong>\n',G)
length = L(LENGTH==G,:);
fprintf('\t\t\t\t\t\t\t\t\t <strong>SORTED WEIGHT</strong>\n')
[Weight, c] = unique(length.WEIGHT);
display(length(c,:))
end
end
The results in command window is here, but in workspace / variables on show the last loop / data.

You should show us your loop of code.

What is it you are trying to store? The formatted output? L? Length? b? LENGTH ? l? Weight? c?

Hi,
In your code variables are updated in every iteration in both outer and inner loop, variables values are not saved in every iteration to any file whereas values stored in variables are overwritten.
Hence only last sorted values are saved. In the variable named ‘length’ only last sorted category value is saved and in the variable named ‘L’ last sorted port (both the categories) value is saved.
To save the whole data either write in a file (as you are already using ‘fprintf’ function) or keep adding rows to an existing table.
For writing to a file please refer: https://www.mathworks.com/help/matlab/ref/fprintf.html
For adding rows to an existing table please refer: https://www.mathworks.com/help/matlab/matlab_prog/add-and-delete-table-rows.html
Hope this helps!

The link about add-and-delete-table-rows has three examples.
