Use variable in two different functions

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

Answer 1

[Azzi Abdelmalek]

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

get the variable var1 from fcn1 and use it in fcn2

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

I didn't get the idea.. Please can you give me an example

As Azzi says, just use the first function to create/return the first variable and pass that into the second function call.

If that's not clear enough show us your problem instead...and what you tried.

[Azzi Abdelmalek]

%function 1
function y=fcn1(u)
var1=2*u
y=vars1+5

% function 2
function s=fcn2(x)
s=sin(x)^2

Now you need to use the variable var1, you have to modify the function fcn1

fucntion [var1,y]=fcn1(u)
var1=2*u
y=vars1+5

now you can get the variable var1 from fcn1

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
