Please replace the content of the file that comes with SDK 2015-1-30 with the following. Basically, the input "file_name" has been renamed as "solar_resource_file". And there is a new mandatory input called "adjust:factor". Developers, please make the necessary changes in the coming release for the sake of the little MATLAB community that uses SAM. (*.m file is attached if anyone is interested)
