These below are part of the contents of the M.file i want to run.
clc;
clear all;
clc;
addpath(genpath('Sample_test'));
addpath(genpath('LFToolbox0.4'));
LFMatlabPathSetup;
%% Step1: Decompress data.C.0/1/2/3---> to get white image data
fprintf('===============Step1: Unpack Lytro Files===============\n\n ');
LFUtilUnpackLytroArchive('Sample_test')
These below are the results in the command.
===============Step1: Unpack Lytro Files===============
Searching for files [ data.C.0 ] in Sample_test
??? Error using ==> textscan
First input must be of type double.
Error in ==> LFToolbox0.4\LFFindFilesRecursive.m at 83
FolderList = textscan(FolderList, '%s', 'Delimiter', pathsep);
Error in ==> LFToolbox0.4\LFUtilUnpackLytroArchive.m at 44
[AllVolumes, BasePath] = LFFindFilesRecursive(InputPath, FirstVolumeFname);
Error in ==> Demo at 23
LFUtilUnpackLytroArchive('Sample_test')

textscan accepts a file id not a file path. Use fopen first

Oh.... I can't say much about older versions of Matlab....
@Huadong Hu, you can try using
FileList = regexp(FileList, pathsep, 'split');
Or
FileList = strsplit(FileList, pathsep);
Hopefully that feature did exist back in 2004

strsplit() is r2013a .
regexp() should be there. However after you use regexp with 'split', it is a good idea to use
dirlist = regexp(FolderList, pathsep, 'split');
dirlist(cellfun(@isempty, dirlist)) = [];
FolderList = dirlist;
If Folderlist had happened to begin or end with pathsep or if there had been multiple pathsep in a row, then regexp split would have left an empty cell; the indexing and cellfun is there to delete those empty cells.

You are using MATLAB R14 from 2004 to attempt to run code that was written for R2014a. The code uses features that did not exist in your release.
