I have to use variable defined in one function in another function. What should I use? I tried global but it fails with me

在 MATLAB Online 中打开

[var1,...]=fcn1(...)

get the variable var1 from fcn1 and use it in fcn2

[...]=fcn2(var1,...)

You could precise that you are using Guide Matlab. you can share data with guidata function

function btnVisualDataset_Callback(hObject, eventdata, handles)
[filename, pathname] = uigetfile('*.xlsx','Load Dataset');
if filename==0
  msgbox('Please Choose Dataset','Error','Error')
  return
end
for i=1:10
data = xlsread(filename);
mv{i}=[data(:,i)];
handles.mv=mv;
guidata(hObject,handles)
end
function btnSearch_Callback(hObject, eventdata, handles)
mv=handles.mv
end
