You're trying to multiply a 2-D matrix by a 1-D column vector that goes from 1 to the number of rows. This will not work in R2015a but will work in later versions where implicit expansion of the column vector to a 2-D matrix will occur. Please upgrade or else use a for loop to do the multiplication
% First way using implicit expansion
birincifaz = randi(9, 3, 5)
newM = birincifaz.*(1:size(birincifaz,1))'
% Alternate way using a for loop
[rows, columns] = size(birincifaz)
newM = zeros(rows, columns);
for col = 1 : columns
for row = 1 : rows
newM(row, col) = birincifaz(row, col) * row;
end
end
newM
