Need help for the following code, i'm getting subscript indices error..
if true
% sample_ind = cell(1,NumAct);
OneActionSample = zeros(1,NumAct);
for i = 1:NumAct
action = TargetSet((i-1)*2+1:i*2);
action_dir = strcat(file_dir,action,'\');
fpath = fullfile(action_dir, '*.mat');
depth_K2_dir = dir(fpath);
ind = zeros(max_subject,max_experiment);
for j = 1:length(depth_K2_dir)
depth_K2_name = depth_K2_dir(j).name;
sub_num = str2double(depth_K2_name(6:7));
exp_num = str2double(depth_K2_name(10:11));
ind(sub_num,exp_num) = 1;
load(strcat(action_dir,depth_K2_name));
depth_K2 = depth_K2(:,:,frame_remove+1:end-frame_remove);
[front, side, top] = depth_K2_projection(depth_K2);
front = resize_feature(front,fix_size_front);
side = resize_feature(side,fix_size_side);
top = resize_feature(top,fix_size_top);
TotalFeature(:,sum(OneActionSample)+j) = [front;side;top];
end
OneActionSample(i) = length(depth_K2_dir);
sample_ind{i} = ind;
end
TotalFeature = TotalFeature(:,1:sum(OneActionSample));
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% You may consider to save the training and testing samples for speed.
% save(strcat(ActionSet,'.Features.mat'), 'TotalFeature');
%
% Load the feature file if there isn't going to be any changes on the
% feature set.

end
Subscript indices must either be real positive integers or logicals.
Error in NewTest2 (line 63) ind(sub_num,exp_num) = 1;

Check the values of sub_num and exp_num. Your problem should then become clearer.

Step through your code and look at the list of file names returned by dir. One of them is not conforming to your expectation that characters 6:7 or 10:11 are strictly positive integers. Since you're converting these characters to numbers and then use these numbers as indices, if this expectation is broken, your program fails.
You can always add a check before using these indices:
...
exp_num = str2double(depth_K2_name(10:11));
if exp_num < 1 || sub_num < 1 || mod(exp_num, 1) ~= 0 || mod(sub_num, 1) ~= 0
%do whatever you want when expectation is broken
warning('file %s does not conform to expectations. Skipping', depth_K2_name);
continue;
end
ind(sub_num,exp_num) = 1;
...

What has this got to do with your original question? Your code does not even have a multiplication that could generate this error.
With such an unspecific question, the only reason I can provide is that the inner matrix dimensions don't agree (as the error message tells you).
Perhaps, you meant to use .* instead of *. Who knows?
