I don't think enviread is a function provided by mathworks. It appears it is something that users have provided.
Try multibandread() function of matlab to read ENVI files. I use this function when I am reading ENVI files and it works very well. If you want some instruction on how to use it to read ENVI files, the following is a good resource.
