Counting number of rows in a field of structure

Hi all!

I need to know how many rows are in a structure field.

The number of rows are not fixed. I try to use numel for counting the numbers inside any row but doesn't work.

I try too with size function but doesn't work either.

• * Message error: too many input/output arguments.**

How can i solve this?

Thanks for all!

Well, that's an ambiguous question if ever were one...certainly for a given structure/field combination size works; we need to see an example of

1. the structure in question
2. what you tried

>> s.f1=rand(3);     % a sample structure with field f1
>> nr=size(s.f1,1);  % number of rows in field content
ans =
   3
>>

Thanks for your answer.

I solve the problem with other loop in other part of the program.

But i'm interestin in to know how can i do to an other way.

I attach an image about my structure.

Thanks in advance for your support.

Nothing attached; what would be better instead would be a .mat file containing a (small) set of the struct and a description of what you're try to retrieve and what you tried...we can't do anything with an image.
