Hello I'm beginner.
I have 20 MATfiles with different names, I want to load some data from 10 MATfile only into table. For example, in a MATfile there are variables :
date, month, year, tkp, tpp, etc...
And I want to load data date, month, year only from just 10 MATfile into table :
| No | Date | Month | Year |
| 1 | 01 | February | 2013 |
| 2 | 21 | Februari | 2013 |
............................
| 10 | 29 | Februari | 2013|
Please help me.

matFiles = dir('*.mat'); table = []; for i = 1:length(matFiles) eval('load(matFiles(i))'); table{i,1} = num2str(i); table{i,2} = num2str(date); table{i,3} = month; table{i,4} = num2str(year); end

??? Error using ==> load
Argument must contain a string.
Error in ==> Menu_Rekap_Data>b_tampilkan_Callback at 81
eval('load(matFiles(i))');

remove the command
eval('load(matFiles(i))');
and use
str = matFiles(I).name; load(str);
I think this should work
??? Undefined function or variable 'date'.
Error in ==> Menu_Rekap_Data>b_tampilkan_Callback at 84
uitable1{i,2} = num2str(date);
variable date, month, year are delare in other GUI and saved into MATfile. I always load data using "uigetfile". I don't know how to declare variablw without it.
And this project run when the user push the button, then data will display in the table, without searching in the directory..help me
I have 20 MATfile in the same directory, I only need to load variable from these bellow : (MATfile name)
JUM01022013, KAM21022013, JUM22022013, ,.. (only 10)
each file contains variable :
date, month, year, tkp, tpp,...
I make another GUI, contain 1 pushbutton and 1 uitable. And I hope when I push the button, the table will display like what I describe before...
