Hello every one, I have a problem regarding raster file in Matlab. My task is import the raster file about temperature to Matlab, then create a formula to calculate a parameter using data from that temperature raster file. Could you explain me how to import raster file and write the formular? The formula is in below, all of data are constant, I just need to put GDDakt (the value of temperature raster file) in. Thank you a lot.
