Perception based Image Quality Evaluator (PIQE) not working?

I want to check Perception based Image Quality Evaluator (PIQE) for more description see the link PIQE

but not working.How to overcome this issue. The picture is attached with code and error.The code is given as following.

 A = imread('Ours_Orignal\1.png');
 Anoise = imnoise(A,'Gaussian',0,0.05);
 Ablur = imgaussfilt(A,2);

 score = piqe(A);
 score_noise = piqe(Anoise);
 score_blur = piqe(Ablur);

 figure
 montage({A,Anoise,Ablur},'Size',[1 3])
 title({['Original Image: PIQE score = ', num2str(score),'    |    Noisy Image: PIQE score = ', num2str(score_noise),'    
 ' ...
    '|    Blurred Image: PIQE score = ', num2str(score_blur)]}, 'FontSize',12)

This inbuilt function piqe Introduced in R2018b

Which Matlab version you are using?

[Haseeb Hassan]

I am using Matlab R2016b Version

[KALYAN ACHARJYA]

That's why this inbuilt function does not work in your Matlab version.

Hope My answer cleared your doubt.

[Haseeb Hassan]

Yes.I have installed 2018 and PIQE is working in it.
