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

Question

Hi this is my code,

experiments(1).num = 33;
experiments(1).code = 'x';
experiments(1).weights = [200.34 202.45];
experiments(1).height.feet = 5;
experiments(1).height.inches = 6;
experiments(2).num = 11;
experiments(2).code = 't';
experiments(2).weights = [111.45 111.11];
experiments(1).height.feet = 7;
experiments(1).height.inches = 2;

I get this error whenever I run it,

Unable to perform assignment because dot indexing is not supported

for variables of this type.

Error in experimentsinitialization (line 4)

experiments(1).height.feet = 5;

When I try to call height of experiments(1), I get this,

>> experiments(1).height

ans =

5 6

However, I must get something like this,

>> experiments(1).height

ans =

feet: 5

inches: 6

What should I replace? or add?

Thank you in advance!

Answer 1

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.
