Compare 2d array with multiple numbers at same time and get the position
显示 更早的评论
Hi, I am trying to find a way to compare a 2d array with different numbers and get the position of the elements at same time without a loop.
I know I could use 'find' function to get the position contain different value use a for loop but I can't use it simultaneously since the length of positions is different.
x=10;
array=randi(10,10)
for i=1:x
[order]=find(array==i);
% some calculation with the order and array here
end
So I could manage this with a for loop but its quite slow, is there a better way to achieve this?
Thanks

Try this:
[rows, columns] = find(array == x);
