Structure inside a while loop && pixel distance

I want to create a structure that stores my array inside a loop

for Example Every time it will generate a data stored in result array. let's say, I have N result. I want to stored into a 1XN structure. How to do that inside a loop?

I have tried for i=1:10

second Qusetion, For example, I have a M x N array. a pixel (m,n) And I used j=(n-1)*M+m convert pixel into the order in Array(:) Is there a way to know the distance between two pixels?

like (3,2) and (3,3) just have 1 unit distance

s=struct('num2str(i)',{result})

But it won't work

Thanks

Something like this?

N = 10;

YourStructure(N).result = zeros(15); % Initialize the structure

for k = 1:N

      YourStructure(k).result = rand(15); % store your array in the structure;

end

EDIT:

To use a while loop (I based my previous answer on your for-loop sorry):

N = 10;

YourStructure(N).result = zeros(15);

k = 1;
while k<=N

      YourStructure(k).result = rand(15);

      k = k+1;
  end

======= For your 2nd question, the distance is calculated like so:

Distance =sqrt((y2-y1)^2+(x2-x1)^2)

with the coordinates of the pixels being [x1 y1] and [x2 y2].

You are trying to create field names named 1,2,3 ... but that is not possible because the field name have to start with a letter.
