Hi
Ive made a gui with alot of editboxes, and made a save button that saves the data I've put into the edixboxes, to a .mat fil.
The mat fil is a matrix due to the many edixboxes.
But now I want to make a load button.
load(uigetfile('*.mat','Select the MATLAB code file'));
This is what I have, but it doesn't load my data into the editboxes.. What more do I need to write? I have 40 editboxes.

I have to make a bunch of assumptions about how you are representing your values.
[filename pathname] = uigetfile('*.mat','Select the MATLAB code file');
L = load( fullfile( pathname, filename ) );
varnames = fieldnames(L);
fieldvals = L.(varnames{1}); %GUESS: you only have 1 variable in .mat
%GUESS: the one variable is a vector of numeric values
%GUESS: you have a vector of edit box handles
%GUESS: and each box is to get the textural representation of one value
for K = 1 : length(fieldvals)
set( YourEdithandles(K), 'String', num2str( fieldvals(K) ) );
end

I'm a bit lost, when you make the code general, then I don't know what to change. So the biggest help you could do for me is make it specifik for my problem. if we start from what I've made with the two matrix [3x3] and [2x2] which are called Load_soil = [3x3] and Load_dim = [2x2]
If I want to get the number 5 from the load_soil matrix into my editbox 5. What do I write?

[filename pathname] = uigetfile('*.mat','Select the MATLAB code file');
L = load( fullfile( pathname, filename ) );
fieldvals = L.Load_soil;
for K = 1 : numel(fieldvals)
set( YourEdithandles(K), 'String', num2str( fieldvals(K) ) );
end

I think I understand you, but what do I type?
NaN -34 NaN NaN NaN NaN NaN NaN NaN NaN
The first line from my matrix looks like this, so if I only take that one, its a vector.
But what do I load?
YourEditHandles5 = [handles.edit1]; <--- I tryed that, but It just gave me the 1,1 = NaN and not the -34
I need something to type infront of it.
like:
YourEditHandles5 = [xxxxxxxx.xxxxxx handles.edit1];
Help
Ive tryed NaN or 0 but nothing helps, it has to be a handle

This is the error I got
??? Index exceeds matrix dimensions.
Error in ==> boetten>load_Callback at 1500 set( YourEditHandles5(K), 'String', num2str( fieldvals5(K) ) );
Error in ==> gui_mainfcn at 96 feval(varargin{:});
Error in ==> boetten at 51 gui_mainfcn(gui_State, varargin{:});
Error in ==> @(hObject,eventdata)boetten('load_Callback',hObject,eventdata,guidata(hObject))
??? Error while evaluating uicontrol Callback
