dbhole.mat contains 334 files. each files consists of [2xn] data. i sort these files with name starting with 'd' and fixed 'h2'. if h2 is not fixed, then what will be the code for doing this?

selectedvariables = sprintfc('d%dh2', 1:14);
[~, location] = ismember(selectedvariables, fieldnames(s));
c = struct2cell(s);
c = c(location);

if h2 is not fixed. i want to sort each 'd'followed by numeric and each 'h' followed by numeric

note: sprintfc() is undocumented.

please tell me the other approach , how to do it?

i had used another code , but i does not show exact result which i want.

for i=1:14
for j=1:16
     data_2hole{i}=mat2cell(eval(['d',num2str(i),'h',num2str(j)]),length(eval(['d',num2str(i),'h',num2str(j)])));

data= (data_2hole{j,i}{1,1}')
end
end

please tell me how to run all the 'h' contained in each d

I would organise the data into a 2D cell data{}{} and work with this structure.

load dbhole.mat
W = whos('d*h*');

for i = 1:numel(W)
  name = W(i).name;
  idx = sscanf(name,'d%dh%d');

    cmd = sprintf('data{%d}{%d} = %s;', idx(1), idx(2), name);
    disp(cmd)
    eval(cmd)
  end

% plot the data
for i = 1:numel(data), plot(data{i}{1}), hold on, end
