classdef data

properties (SetAccess = 'public' ,GetAccess = 'public')

Name

end

d1 = data();

d2 = data();

d3 = data();

d1.Name = 'data1';

d2.Name = 'data2';

d2.Name = 'data3';

% object array

mylist = [d1 d2 d3]

% asking user to input a name

userInput = 'data2'

% return a index number from 'mylist' based on the name of "userInput"

% ??

I need to check "mylist" and go through objects in that list and check which object has the name == userInput and return the index of that object. In this case return 2

One way:

d1.Name = 'data1';
d2.Name = 'data2';
d3.Name = 'data3';
d4.Name = 'data4';
d5.Name = 'data5';
d6.Name = 'data6';
mylist = [d1 d2 d3 d4 d5 d6];
userInput = 'data2';
strcmp( {mylist.Name}, userInput)
ans = 1×6 logical array
   0   1   0   0   0   0
