I want to add to a 3D array using a for loop without changing the previous values. I created an empty 3D array by writing:
Then i wrote a for loop to append to that array the index number of when the if statement is satisfied, in the correct 3rd dimension
for 3Dimages=1:100
for i=1:512*inputofuser
if Original3Dimage(i,:,3Dimages)==0
Array=[Array(:,:,3Dimages),i];
else
break
end
end
end
I know if this was 2D, it could be done by saying Array=[Array,i] but i want this to be done in 3D such that depending on which of the 1:100 3Dimages the for loop is in, it creates a row of i values in the same 1:100 3Dimages page of the Array.
Example:
when 3Dimages=1
lets say the true statement occurs at an i value of 1,2,3,4,5
then when 3Dimages=2, the true statement occurs at an i value of 6,7
then when 3Dimages=3, the true statement occurs at an i value of 10,11,12
therfore Array in this 3Dimages=1:3 smaller example would have a size of 1 5 3 where:
(:,:,1)= [1 2 3 4 5]
(:,:,2)= [6 7 blank blank blank]
(:,:,3)= [10 11 12 blank blank]
