Imwrite double
WebMay 30, 2016 · imwrite (A,filename) writes image data A to the file specified by filename. If A is of data type uint16 and the output file format supports 16-bit data (JPEG, PNG, and TIFF), then imwrite outputs 16-bit values. So you can multiply A by 100 then and then convert it to uint16. You will get [1200 1350;1500 10775].
