Matlab question: usage of save -


in following matlab code, 

random_numbers = randn(1,1000); j=1; i=1:length(random_numbers) if random_numbers(i) > 2.0 extracted(j) = random_numbers(i); j = j + 1; end end save 'sample1' extracted

we following error:

??? error ==> save unable write file sample1: permission denied.  error ==> test @ 9 save 'sample1' extracted

please advise.

a permission denied error suggest trying save directory not have write permission. since have specified base name filename, save try save mat-file current working directory, can determine running command pwd. can check permissions of current directory running

[success, message] = fileattrib

and inspecting userwrite field of returned message.
