could you show the snipet of your code where 'save' occurs

thomas thanks for answering.
%% Split the dataset to create a Training and Test set
% The dataset is divided into two sets, a _training_ set which includes
% data from 2004 to 2007 and a _test_ set with data from 2008. The training
% set is used for building the model (estimating its parameters). The test
% set is used only for forecasting to test the performance of the model on
% out-of-sample data.
% Create training set
trainInd = data.NumDate < datenum('2008-01-01');
trainX = X(trainInd,:);
trainY = data.SYSLoad(trainInd);
% Create test set and save for later
testInd = data.NumDate >= datenum('2008-01-01');
testX = X(testInd,:);
testY = data.SYSLoad(testInd);
testDates = dates(testInd);
save Data\testSet testDates testX testY
clear X data trainInd testInd term holidays dates ans num text
??? Error using ==> save
Unable to write file Data\testSet: No such file or directory.

You would get that error if you did not have a subdirectory named "Data" in your current directory.

Your code would be more robust if you had a special folder for your data files and didn't mix your data files in with your m-files, fig files, and other files. Learn how to use uigetdir(), uigetfile(), fullfile(), exist(), and mkdir().

try
save('testSet.mat','testDates', 'testX' , 'testY') %to save it in the current directory
or create a directory called Data and use
save('Data\testSet.mat','testDates', 'testX' , 'testY') % to save in Data dir
or just add the follwing in a line above the save command
mkdir('Data'); % this should create the data directory
