Display String Arrays in a Listbox
显示 更早的评论
Hey Guys,
I am a Matlab-Newbie and I have a smale Problem, which I can not solve.
I have 9 String Arrays (all different size) and I want to display them all in one Listbox. The Arrays are saved in an .mat-file. So I need to Load() them and then displazy them all in my Listbox. I would be really tankful if anyone of u could help me. ( and ignore my eng.Skills)
And can u pls answer me the general Question: How can I add things to my Listbox without killing the content, which is allready added.
PS: the command '-append' means the 'save' command does not overwrite an existing mat-file. It just adds new content. Need sth like this for my listbox.

If you want to load a listbox with the contents of 9 string arrays, then (assuming you are using GUIDE to build your GUI) you can load the listbox in your GUI/figure's yourGuiName_OpeningFcn method (where yourGuiName is the name of your GUI)
% load the data from the mat file
load('s1.mat');
load('s2.mat');
% concatenate the string array data into a cell array
data = [cellstr(s1) ; cellstr(s2)];
% load the cell array into the listbox (assumed to be named listbox1
set(handles.listbox1,'String',data);
The above example is for two string arrays only. We use the cellstr on each array to convert the array into a cell array to allow for the concatenation into a cell array since that is the format for the selections into the listbox. If any of the 9 string arrays are already cell arrays, then you can ignore this conversion.
Now in order to append new data to the listbox selections, you can do the following
% get the cell array data that contains all the selections in the listbox
data = get(handles.listbox1,'String');
% append the new data
data = [data ; cellstr('blue')];
% reset the selections
set(handles.listbox1,'String',data);
Try the above and see what happens!
