How to delete even Index from array and replace zero at the end MATLAB

I have the code which delete 5% of random index from the dataset and add zero at the end .

i just want to delete even index sample from the array and add zero at the end

discard= delete the random sample from array

load('datasetvalue.mat')

[M,N] = size(dataset) ;
percentageMP=5;
size_MP=round(percentageMP/100*N);
Discards=zeros(M,size_MP);
for i=1:M
    MP=dataset(i,:);
    
    discard=randsample(N,size_MP);
    MP(discard)=[];
    MP(:,end+1:N)=0;
    MPV(i,:)=MP;
    Discards(i,:)=discard;  
end

"delete even index sample from the array and add zero at the end"

Maybe:

X             = rand(10, 10);  % Arbitrary test data
X(2:2:end, :) = [];            % Delete rows with even indices
X(10, 10)     = 0;             % Fill with zeros implicitly
