Let's say I have a variable called 'test'. test is a 1x2 struct array with 2 fields - Name and Value.
test =
1×2 struct array with fields:
Name
Value
When I open the variable 'test', this is how it looks. Each of the fields have 2 values (2 pairs of name-value pair)
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/738684/image.png)
How can I extract just the value of the name 'long_name' without using positional index?
Using positional index, I can do it using the following code
test(2).Value
But I want to use the name string 'long_name' to find the corresponding value, as the 'long_name' may not always be at the 2nd position in other variables like test.
Any leads on how I could do that?
Thanks!

test = struct('units', {'degrees_east', 'degrees_north'}, ...
'long_name', {'longitude', 'latitude'})
theNames = {test.long_name};
findSpecificName = ismember(theNames, 'longitude');
T = test(findSpecificName)
q = test(ismember(theNames, 'latitude')).units
