From what I understood from your question I think the following code solves your question
% Define the row of digits
row = [10, 0, 25, 22, 45, 0, 0, 0, 0, 0, 0, 1, 3, 21];
% Find the positions greater than zero values
positions = find(row > 0);
% Create an array of new integer values
new_values = [60, 20]; % Example new integer values
% Replace the values at the identified positions with new integer values
row(positions) = new_values(1:length(positions));
% Keep the remaining positions as zero
row(row == 0) = 0;
% Display the updated row
disp(row)
Note:This code assumes that the number of positions greater than zero values is the same as the number of new integer values provided. If the number of positions is greater, the extra positions will remain as zero. If the number of positions is fewer, the remaining new values will not be used.
