Something like that should work:
folder = 'path_of_your_folder/'
data = dir(folder);
idx = 1;
for n = 1:length(data)
if ~data(n).isdir
filename{idx} = [folder data{n}.name]
idx = idx+1;
end
end

The simple MATLAB approach is to use a comma-separated list. To avoid the dot-directory names and any other files and folders, it is strongly recommended to specify a filename including wildcard and extension:
F = 'path_of_your_folder';
S = dir(fullfile(F,'*.mat'));
C = {S.name} % much simpler and more efficient than your loop

Try this:
% Process a sequence of files.
folder = pwd; % Or wherever you want.
filePattern = fullfile(folder, '*.mat');
fileList = dir(filePattern) % Create a structure array.
% Get all filenames into one cell array. Filenames have the complete path (folder prepended).
allFileNames = fullfile(folder, {fileList.name});
% Loop over all filenames to process them somehow.
numFiles = numel(allFileNames);
for k = 1 : numel(allFileNames)
% Get this file name.
fullFileName = allFileNames{k};
fprintf('Processing %s\n', fullFileName);
% Now do something with fullFileName, such as passing it to load.
end
