How to extract component of vector from a struct with fields across each field
76 views (last 30 days)
It is more clear if I show you my specific case (see image below).
Let's assume that I created my struct variable called "Database" with many fields (e.g. measurement number).
Is there a simple method to get a 1D vector with the second element of Database.DisplAtReferenceTemperature, across all the fields?
I wonder to have a result equal to
[4712.9 5241.9 5681.2 6053.6 9305.8]
I tried the command
but does not work.
The "brute force" solution is to crete a for loop that scan all the fields, but in my opinion is not very efficient.

To extract all element from the DisplAtReferenceTemperature fields, add square brackets (or curley brackets to store values in a cell array).
data = [Database(:).DisplAtReferenceTemperature];
To extract the 2nd element of DisplAtReferenceTemperature from each structure in the array Database,
data = arrayfun(@(i)Database(i).DisplAtReferenceTemperature(2),1:numel(Database))
