How to convert my function for GPU (Cuda) and run it on GPU

Hello, I hope you are doing well, I have the following function i want to convert it into cuda so it can run on GPU or any other Embedded Device

Can anybody Please help me with this

I also Attached My dataset for this

function [Score] = Scorefunction(Dataset,clusternumber)

dataset_len = size(Dataset,1);
Score = zeros(1,clusternumber);
for j=1:clusternumber
    [cluster_assignments,centroids] = kmeans(Dataset,j);
    distance_within=zeros(dataset_len,1);
    distance_between=Inf(dataset_len,j);
    for i=1:dataset_len
        for jj=1:j
            boo=cluster_assignments==cluster_assignments(i);
            Xsamecluster=Dataset(boo,:);
            if size(Xsamecluster,1)>1
                distance_within(i)=sum(sum((Dataset(i,:)-Xsamecluster).^2,2))/(size(Xsamecluster,1)-1);
            end
            boo1= cluster_assignments~=cluster_assignments(i);
            Xdifferentcluster=Dataset(boo1 & cluster_assignments ==jj,:);
            if ~isempty(Xdifferentcluster)
                distance_between(i,jj)=mean(sum((Dataset(i,:)-Xdifferentcluster).^2,2));
            end
        end
    end
   
    minavgDBetween = min(distance_between, [], 2);
    silh = (minavgDBetween - distance_within) ./ max(distance_within,minavgDBetween);
    Score(j) =mean(silh);
end
end

Do you need to deploy to an embedded device or just run on GPU on the desktop? Because you can just use PCT's gpuArray.

Hi,

MATLAB has quite a few coder apps to generate specific code from MATLAB code.

To generate GPU code, you can make use of the GPU Coder.

To generate Embedded Code, you can use the Embdedded Coder.

If you wish to learn more about GPU coder and Embedded coder, please check out the MathWorks documentation links below:

@Arka It does not help thats why i posted question here.

[Arka]

What is the issue that you are facing?

@Arka I am unable to convert it into cuda, I want to write a Code for this

What have you tried till now, and what is the error that you are encountering?
