hello, i need to load specific data from my mat file to gui table u can see mat file in the picture https://www.mathworks.com/matlabcentral/answers/uploaded_files/85736/image.png i need to show specific data,
load Data_Plat.mat
[row,~] = size(Database_All);
data2 = cell(row,4);
for n = 1:row
data2{n,1} = Database_All.Plat{n};
data2{n,2} = Database_All.Nama{n};
data2{n,3} = Database_All.Jurusan{n};
data2{n,4} = Database_All.Status{n};
this is my code for show all data from mat file in to gui table, the question is, how can i just show 1 data, for example, data with number plat DD6713MT

Firstly, a much simpler version of your original code:
data_plat = load('Data_Plat.mat');
Database_All = data_plat.Database_All;
data2 = table2cell(Database_All(:, {'Plat', 'Nama', 'Jurusan', 'Status'}));
set(handles.uitable1, 'Data', data2);
If you want to filter your table to only include the rows that match a certain value, replace the : above by your filter, eg.:
data2 = table2cell(Database_All(strcmpi(Database_All.Plat, 'DD6713MT'), {'Plat', 'Nama', 'Jurusan', 'Status'}));

I have no idea what the above sentence is saying, particularly "the car has pass away"

If you are asking how to get the value of row 1 column 2 of your data2 cell, try
no_plat = data2{1,2}; % get row 1 column 2 value of data2

its still erorr Attempt to reference field of non-structure array.
Error in contoh>pushbutton1_Callback (line 86) idx = find(strcmpi('DD6713MT',data2.Plat));
can u tell me how can i use that code, i put that code in inside for n try too in out side for, ty for u attention buddy

find is rarely needed. In particular:
idx = find(somelogicalexpression);
result = somevector(idx);
is the same as
result = somevector(somelogicalexpression);
The latter being faster as well.
