I am designing the GUI using the matlab app builder, I want to change(assign) the values of struct which is already present in the workspace using the GUI , but I have used the assignin function for 'variables' its works well but for the 'struct' I dont know how to change.
I want to change the car.year value from the GUI.

A struct variable is a variable, just as any other...
function testit(s)
v=inputname(1);
s.year=s.year+10;
assignin('base',v,s);
end
Illustration --
>> car=struct('year',2020,'loan',25000,'counts',10)
car =
struct with fields:
year: 2020
loan: 25000
counts: 10
>> testit(car)
>> car
car =
struct with fields:
year: 2030
loan: 25000
counts: 10
>>
