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

structure dot indexingtext strings

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?

Best Answer

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'

The code you posted is self-consistent. However, in some earlier code, you set

experiments(1).height = [5 6]

and you did not remove that.

My guess is that you modified your code along the way, but you did not clear the experiments variable so it still has the old data around.

I cannot reproduce your problem. This works

%%
parameter.A = [];
a = ones(1,5);
parameter.A = [parameter.A; a];
b = 2*ones(1,5);
parameter.A = [parameter.A; b]

and outputs

>> parameter = 
  struct with fields:
    A: [2×5 double]
    
>> parameter.A
ans =
     1     1     1     1     1
     2     2     2     2     2
