How to check whether a specific variable is empty or not in table type

17 views (last 30 days)
Hi, please see the follwing figure.
As you can see, in this 'table' type variable, some rows does not have 'ls_max_tone' and some have 'ls_max_tone' .
'ls_max_tone' variable is defined as 'cell' type.
I can find which row has 'ls_max_tone' variable using for loop. However, I know this is not efficient way.
Is there any efficient way such as
T_data(T_data.temperature >50, :)
which returns all rows that temperature value exceeds 50.
Thanks in advance.

T_data(~cellfun(@isempty, T.ls_max_tone),:)
This will return a table containing only the rows where ls_max_tone is not empty.
