How to run this loop and make sure the information from a struct is assigned as a simple m x n x k ? My loop is overwriting the information

I am trying to have the N vector as an m x n x k extracting the information from a struct suite

but the loop here is being overwritten. How can I avoid the overwriting in this loop?

if isempty(locations) || nargin==2

locations = find([Suite(:).active]); %active locations [1 2 4 6]

end

for loc = 1:13

if Suite(loc).active

for i=locations

M=zeros(size(Suite(i).scani,1), size(Suite(i).scani,2), length(find([Suite(i).active])));

k=1:length(locations)

M(:,:,k)=Suite(i).scani;

N(:,:,k)=M

end

DDD1=N(:,:,1);

DDD2=N(:,:,2);

DDD3=N(:,:,3);

DDD4=N(:,:,4);

end

end

It's kind of unclear what you're trying to do here, but I'm guessing you want to be doing "N(:,:,i)=" instead of "N(:,:,k)=" since k should be the same no matter which iteration you're on. There's a few other problems I think I see, but I'm not really sure what the code is trying to accomplish so I can't say for sure.

I have information stored in a suite where each location is able to store velocity in (rows indicating time, columns indicating heights). The only active locations are 1 2 4 and 6. However I want to extract that information from the suite so that I have it as a normal matlab matrix Velocity(rows,columns, pages) so that each page takes the location.

The length of location will give me the right order 1 2 3 4 as I wish the pages to be stored but the suite has the information in locations 1 2 4 and 6. I tried to do a double loop but the information is all being overwritten. Then the size of the first 2 locations has 15600 rows but the last two rows have a size of 20800 so preallocating is also an issue.
