I created a folder using "mkdir", however I can't write files at this folder because the I don't have the permission, the folder is only for read. How to create folder with permission to write?

Rather than looking at the permission, look at the directory attribute. I realized that I had used mkdir to create a folder and, for some reason (I suspect it had to do with accidentally using a cell of strings as one of my inputs to create the folder), the directory value was set to zero. When I made the same name directory by hard coding it, the directory attribute was set to 1 and, all of a sudden, I could write files where before it would not allow me. I know this question is old, but I'm providing the answer now for anyone else who runs across this issue and struggles to find an answer like I did.

When you use fileattrib, catch the success and the error message also:
[status,msg,msgID] = fileattrib('D:\work\results','+w')
What do you get? You cannot change the permissions of a folder, if you do not have write permissions to it. Actually you should not even be able to create a folder without write permissions. So how did you create it at first?
Will the problem occur repeatedly? If not, use the Security tab in the "Properties" of the folder, which appears in its context menu in the Windows Explorer. Perhaps the permissions of D:\Work are restricted already. Then fix this folder also.
