I want to define a enumerated data type (eMatType) which consists of the following definitions :
STEEL = 1
CONCRETE = 2
ALUMINUM = 3
Now, once that data type is created, how can I use it to declare a variable. eg. if I want to delclare a variable as 'double', I use x = zeros(1,1,'double')
How can I declare a variable with the new enumerated data type?
Thanks.

Do you mean something like this?
x = nominal([3:-1:1,1,1,3],{'Steel','Concrete','Aluminum'})

Thanks, but I am looking for creating a new instance of a enumerated data type.
for example, if you want to initialize a variable of the type string, you write:
x = '';
if you want to initialize a variable of the type 'int32', you write:
y = zeros(1,1,'int32');
I am looking for a way to initialize a variable of the new enumerated data type 'MatType' where the class definition for 'MatType' is:
classdef(Enumeration) MatType < Simulink.IntEnumType
enumeration
MATERIAL_STEEL(1);
MATERIAL_CONCRETE(2);
MATERIAL_NODESIGN(3);
MATERIAL_ALUMINUM(4);
MATERIAL_COLDFORMED(5);
MATERIAL_REBAR(6);
MATERIAL_TENDON(7);
end
end
