I have to concatenate the path and file name but the following error is coming as given below:
path = 'E:\Ob_Extraction\peta\PETA dataset\3DPeS\archive\';
allFiles = dir( 'E:\Ob_Extraction\peta\PETA dataset\3DPeS\archive' );
allNames = { allFiles.name };
image = imread(strcat(path,allNames(3)));
Error using imread>parse_inputs (line 457)
The file name or URL argument must be a string.
Error in imread (line 316)

how do i solve it ?
I want to use video from following directory
'E:\Multimedia Security\matlab\UCSD_Anomaly_Dataset.v1p2\UCSDped1\Train\Train001'
Following is the code which i wrote
close all
clear all
clc
workingDir = 'E:\Multimedia
Security\matlab\UCSD_Anomaly_Dataset.v1p2\UCSDped1\Train\Train001';
videoofReader = vision.VideoFileReader(dir(fullfile(workingDir, 'abc.avi')));
videoPlayer = vision.VideoPlayer;
while ~isDone(videoofReader)
frame = step(videoofReader);
step(videoPlayer, frame);
end
release(videoofReader);
release(videoPlayer);
Error which i get is
`Error using VideoFileReader.set.Filename (line 139)
Expected Filename to be one of these types:
char
Instead its type was struct.

Error in kl2 (line 18)
videoofReader = vision.VideoFileReader(dir(fullfile(workingDir, 'abc.avi')));
System prompts you Error in kl2 (line 18) so this line has a problem. You do not need to use dir because you already have an absolute path.
Give you two solutions:
videoofReader = vision.VideoFileReader(fullfile(workingDir, 'abc.avi'));
dirstruct = dir(fullfile(workingDir, 'abc.avi'));
videoofReader = vision.VideoFileReader(dirstruct{1});
I am attempting to use sysic to create an interconnected system from a number of state space models. However; I keep recieving the same error:
Undefined function or variable "Vk".
Error in sysic (line 212)
[ard,arl,er] = LOCALpass1(Vk);
Error in addOutputWeights (line 62)
sysic
The code used that generates this error is as follows:
systemnames = 'plantModel WControl WError';
inputvar = '[r(4); u(4)]';
outputvar = '[WControl; WError;r- plantModel]';
input_to_WError = '[r-plantModel]';
input_to_WControl = '[u]';
sysoutname = 'instramentedPlant';
cleanupsysic= 'yes';
sysic
This error was caused because input_to_plantModel was not present in the workspace. For every system that is refered to in systemnames there must be a corresponding input_to_X.
The following code runs correctly
systemnames='plantModel wControl wError';
inputvar ='[r(4); u(4)]';
outputvar ='[wControl;wError;r- plantModel]';
input_to_plantModel ='[u]';
input_to_wError ='[r-plantModel]';
input_to_wControl ='[u]';
sysoutname ='instramentedPlant';
cleanupsysic = 'yes';
I want to compile a gui matlab project, but fail because of this error which is not in my code

How can I get matlab (2013b) to compile the package?
The code where matlab fails is (which is NOT my code)
function tf = isscript(files)
% ISSCRIPT Is the file a script file?
tf = false(1,numel(files));
for k=1:numel(files)
pth = files{k};
% Can't be a script if it isn't an M-file.
if strcmpi(pth(end-1:end), '.m') && exist(pth, 'file') == 2
mt = matlab.depfun.internal.cacheMtree(pth);
fcn = mtfind(mt, 'Kind', 'FUNCTION');
tf(k) = isempty(fcn);
end
end
The code will fail for files with a filename of length 1. Either rename all files with such a short filename or change the line to:
if length(pth)>1 && strcmpi(pth(end-1:end), '.m') && exist(pth, 'file') == 2
I am working on extracting features from avi files using MATLAB. Every time I run the code I get an error "Exception in Reading". Code is:
cd('D:\Classified\negative-videos');
neg_files = dir('*.avi');
% compute negative files
for fileIter=1:size(neg_files,1)
tic;
movie_name = neg_files(fileIter).name;
try
[color_score__,edge_score__,spatio_score__,score__] = lg_model(movie_name,fps,3);
if(score__ < threshold)
true_neg = true_neg + 1 ;
end
if(score__ >= threshold)
false_pos = false_pos + 1 ;
end
fprintf('[ %d / %d ]\tFile : %s\tscore : %f\tcolor_score : %f\tspatio_score : %f\n', fileIter,size(neg_files,1),movie_name, score__,color_score__, spatio_score__);
catch ME1
fprintf('[ %d / %d ]\tFile : %s\t EXCEPTION IN READING \n', fileIter,size(neg_files,1),movie_name);
end
toc;
end
fprintf('INTERMEDIATE\ttrue pos = %d \n false pos = %d \n true neg = %d \n false neg = %d \n', true_pos,false_pos,true_neg, false_neg);
What is the problem with the above code snippet?
The stack trace is as follows:
For each of the 18 videos in my directory I get following error:

Apologies for not posing as a comment, but need a little more rep before I'm allowed to.
I agree with #JimInCO, it looks like you don't have VideoReader. It was first introduced in R2010b. You can try using aviread instead if you have an older version.
