Load multiple struct 1x1 mat files

Hey guys!

I am having trouble when trying to load several mat files which consist of RMN images. The files are struct 1x1 and if I try to create a loop for loading files, Matlab loads only the first image in the variable named cjdata.

Has anyone else had this problem and found a solution?

Thanks!

filenames={'1550.mat','1549.mat','1548.mat','1547.mat','1546.mat','1545.mat','1544.mat',...
    '1543.mat','1542.mat','1541.mat'};
for kk = 1:numel(filenames)
    load(filenames{kk})
end

Most likely you just need to use indexing, exactly like the examples here:

It is recommended to load into an output variable, rather than directly into the workspace. doing so also makes your task simpler and easier to understand:

V = 1550:-1:1541;
N = numel(V);
C = cell(1,N);
for kk = 1:N
    F = sprintf('%d.mat',V(kk));
    S = load(F);
    C{kk} = S.cjdata;
end

All of the image data will be in the cell array C.

You can easily adapt this to suit your exact variable class and size: or if this code does not work and you want more help then please upload a sample file.
