issue while concatenating the matrix

This is the code which I am using

%%
clear all
clc

[file_list, path_n] = uigetfile('final*.mat', 'Grab all the files', 'MultiSelect','on');

if ischar(file_list); file_list = {file_list}; end  %only one selected
if ~iscell(file_list); return; end   %user cancel

ii=1
for i = 1:length(file_list)
    
    this_file = fullfile(path_n, file_list{i});
    loadfile = load(this_file);
    s = struct(loadfile);
    h = loadfile.o2a_s ;
    jj = h(:,1);
    z = datenum(h(:,2),'HH:MM');
    h(:,2)=[];
    KK = str2double(h);
    %finding ths number of rows and columns
    [R C]=size(KK);
    % assigning a zero matrix gg of the given size
    gg=zeros(1,5);

    %% everything is working fine as per needed till here but from here i am facing troubles
    
 
    j=1;
    for ii=1:(R-1);
        %%
        if z(ii,1)>= [738522.558] while z(ii,1)<= [738522.566]               
                gg=[gg;KK(ii,:)];
                
            end
            end
    end
end
%  dd(1,:) = [];

the files are in Mat format. the file type is string.

i want values of z in such manner z(ii,1)>= [738522.558] while z(ii,1)<= [738522.566]

the problem is the code is running fine but ti am not able to retrieve the gg matrix at the end. ( rather i am getting the values corresponding to the last file inputted to the loop)

2. I want to include the file name corresponding to the ii value in the gg matrix. how to modify the code for the same ?

if isnumeric(file_list)
    return
end
file_list = cellstr(file_list);

[file_list, path_n] = uigetfile('final*.mat', 'Grab all the files', 'MultiSelect','on');

if ischar(file_list); file_list = {file_list}; end  %only one selected
if ~iscell(file_list); return; end   %user cancel

N = length(file_list) ; 
iwant = cell(N,1) ; 
for i = 1:N
    
    this_file = fullfile(path_n, file_list{i});
    loadfile = load(this_file);
    s = struct(loadfile);
    h = loadfile.o2a_s ;
    jj = h(:,1);
    z = datenum(h(:,2),'HH:MM');
    h(:,2)=[];
    KK = str2double(h);
    %finding ths number of rows and columns
    [R, C]=size(KK);
    % assigning a zero matrix gg of the given size
    gg=zeros(1,5);    
    %% everything is working fine as per needed till here but from here i am facing troubles        
    j=1;
    for ii=1:(R-1)        
        if z(ii,1)>= 738522.558 
            while z(ii,1)<= 738522.566
                gg=[gg;KK(ii,:)];                
            end
        end
    end
    iwant{i} = gg ; 
end

You already have files names in hand.

[Arvind Gauns]

    gg=[]; %zeros(1,5);    
    %% everything is working fine as per needed till here but from here i am facing troubles        
    j=1;
    for ii=1:(R-1)        
        if z(ii,1)>= 738522.559
             if z(ii,1)<= 738522.565
                 gg=[gg;KK(ii,:)];                
             end
        end
    end
    iwant{i} = gg ; 
end

with a little modification, it worked.

Thanks.
