Error Unable to perform assignment because dot indexing is not supported for variables of this type.

Simple code

TestStruct.Level1A='TestStruct_Level1A';

TestStruct.Level1B='TestStruct_Level1B';

TestStruct.Level1B.Level2='TestStruct_Level1B_Level2';

gives error

Unable to perform assignment because dot indexing is not supported for variables of this type.

Error in Sample1 (line 3)

TestStruct.Level1B.Level2='TestStruct_Level1B_Level2';

Why does this work at the first level but not the second? How can I make it work?

You are receiving the error because you have already defined the class of the first level as a character. In order to add a second level to it you would have to define it as a structure.

>> TestStruct.Level1B='TestStruct_Level1B';
>> class(TestStruct.Level1B)

ans =

    'char'
