hello everyone i hope you are doing well
The data in the file is 250x1000, i have implemeneted the following code to delete 5% samples randomly from each row and replace zero at the end to complete the shape 1000 samples
Instead of zero, i want to repeat the array of each row from start complete the shape of 1000.
for example
in row 150 i have a data like data
[200 400 800 1000 800 200 400 ......]
When the below code run it remove 50 samples (950 samples remaining) and add 50 zeros (after 950) at the end of the row.
But i want to repeat the the row from start like [200 400 800 ....] will be added at the end of the row depend on the samples removes
How can i do it ?
[M,N] = size(dataset) ;
percentageMP=5;
size_MP=round(percentageMP/100*N);
for i=1:M
row=dataset(i,:);
row(:,end+1:N)=0;
dataset(i,:)=row;
end

Do you want to replace the zeros with the first values in the row before or after you have randomly deleted 5% of the elements in it?

@Davide Masiello Yeah, i want the first values after deleteing the elements

Replace:
row(:,end+1:N)=0;
by
row(:,end+1:N) = row(1:size_MP);
