this is my code in which i want to laod mat file.
load my_images
load scribbles
if this variable is set to 0, only the final alpha matting is saved. Otherwise, partial results (such as the matting components) are saved.
save_partial_results = 0;
% try to group the matting components for forground/background matting
do_grouping = 1;
% for all examples here we use 50 eigen vectors...
eigs_num=50;
if (1)
nclust =10;
[alpha_comps,alpha] = SpectralMatting(my_images.woman, [], 'woman_', eigs_num, nclust, ...
[], save_partial_results);
end
if (1)
nclust =10;
[alpha_comps,alpha] = SpectralMatting(my_images.face, [], 'face_', eigs_num, nclust, ...
[], save_partial_results);
end
if (1)
nclust = 8;
[alpha_comps,alpha] = SpectralMatting(my_images.kim, scribbles.kim, 'kim_', eigs_num, nclust, ...
[], save_partial_results);
end
if (1)
nclust = 40;
apply_final_enhancement = 1;
[alpha_comps,alpha] = SpectralMatting(my_images.wind, scribbles.wind, 'wind_', eigs_num, nclust, ...
apply_final_enhancement, save_partial_results);
end
if (1)
nclust = 20;
[alpha_comps,alpha] = SpectralMatting(my_images.kid, scribbles.kid, 'kid_', eigs_num, nclust, ...
[], save_partial_results);
end

You don't have code? It looks like code to me. Not very robust code, but it is code. Why not use exist() to check if those files exist first:
% Get the full filename, with path prepended.
baseFileName = 'scribbles.mat';
fullFileName = fullfile(pwd, baseFileName);
% Check if file exists.
if ~exist(fullFileName, 'file')
% File doesn't exist -- didn't find it there. Check the search path for it.
fullFileNameOnSearchPath = baseFileName; % No path this time.
if ~exist(fullFileNameOnSearchPath, 'file')
% Still didn't find it. Alert user.
errorMessage = sprintf('Error: %s does not exist in the search path folders.', fullFileName);
uiwait(warndlg(errorMessage));
return;
end
end
