Hi,
I have created a .mat file made of [266x3] flloats and I am trying to load it using a pushbutton in GUIDE.
Following, MATLAB Answers posts, I wrote:
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
[FileName, PathName] = uigetfile('*.mat','Select mat file');
data = load(fullfile(PathName, FileName));
handles.data = data;
guidata(hObject, handles);
I put a breakpoint inside this function to check the variable 'data'. I get:
K>> data(1)
ans =
data: [266x3 double]
Do you know how am I supposed to access, for example data(1)??
I would want data(1) to return the value in data(1), not information about the variable 'data'
Precision : if I load the .mat file directly in my workspace and ask for data(1), I get:
>> data(1)
ans =
30.2280

请先登录，再回答此问题。

Ok, so I figured it out.
load created a structure so I have to do: data.data(1) to access what I wanted.
Thank you, me!
