what would be the command to save or open a particular excel data.xls with the designation in a particular drive or folder?

xlswrite might be the one, but I don't know how to add the information on the destination to save data. Same question to xlsread to search and read a file.

Here is an example. Make sure that the destination folder exists already. If not or if you have to create destination folders dynamically, use EXIST for testing if they exist already and MKDIR for making them if necessary.

 data   = randi( 10, 5, 3 ) ;
 header = {'A', 'B', 'C'} ;

 % - Build cell array of mixed content (strings and numbers).
 data = [header; num2cell( data )] ;

 % - Concatenate path bits to relevant destination file/folder.
 locator = fullfile( '..', 'Data', 'Measures.xlsx' ) ;

 % - Build Excel file.
 xlswrite( locator, data ) ;

Thank you for your instruction. Can you tell me what '..' indicates in the line :locator=fullfile('..','data','measures.xls')? If I want to designate C drive(assuming I created a folder there), can it be 'c'?

I got the error as below.

>> header={'a','b','c'};
>> data=randi(10,5,3);
>> locator=fullfile('..','data','measures.xls');
>> xlswrite(locator,data);
Error using xlswrite (line 226)

It was for building a path that targets a folder at the same level as the current folder.

Let's try to write to a file in the same folder first, to eliminate the complication of building a path: does the following work?

 header={'a','b','c'};
 data=randi(10,5,3);
 xlswrite('test.xlsx',data);
