I tried to MASK the shapefile of my study area but the matrix of the MASK is only NaN data. so please I need your help. I have attached the script_MASK.
Thank you in advance.

What are the values of your tiff file? It's probably in the range 0-255 so most values will be set to nan because you set all values more than 1 to nan. You might want to set the to nan only if they're outside the range 0-255, or use im2double() to change the range of your image from 0-255 to 0-1.
