[var1,...]=fcn1(...)
get the variable var1 from fcn1 and use it in fcn2
[...]=fcn2(var1,...)

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.

%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
