Maximum and Minimum values of a field structure array

Hi, I have structure array as shown in the image below. How can i find the maximum and minimum population with the corresponding state for the available data.

Thanks in advance.

%find max and min population
[Cmax,maxIdx]=max(AustralianStates.Population)
[Cmin,minIdx]=min(AustralianStates.Population)
%find corresponding state
AustralianStates.Name([minIdx maxIdx])
%find corresponding land area
AustralianStates.Land_Area([minIdx maxIdx])

It is showing as Error using max, too many input arguments. can you help me.

Which version of MATLAB are you using? Can you also share your struct in a mat file?

I believe small modification is needed:

%find max population
[Cmax,maxIdx]=max([AustralianStates.Population]);

%find corresponding state
AustralianStates.Name(maxIdx)

%find corresponding land area
AustralianStates.Land_Area(maxIdx)

FYI, another possible solution to find max population is:

%find max population
T = struct2table(AustralianStates);
[Cmax,maxIdx]=max(T.Population);

Iam using R2019a.

Can you try Akira's solution?

Please find the matlab file attached below.

Hi @Akira Agata,

I tried the first code and i got the below error.

"Expected one output from a curly brace or dot

indexing expression, but there were 8 results.

Error in A2_19508724 (line 108)

AustralianStates.Name(maxIdx)"

Thank you,

Akira's second code is working.

I got the result.
