IA = im2uint16(mat2gray(A, [Tmin Tmax]));

It is my understanding that you want to understand what this code is doing.
As per my understanding, in first line of code the matrix ‘A’ is converted to a grayscale image that contains values in the range 0 (black) to 1 (white). ‘Tmin’ and ‘Tmax ’ are the values in A that correspond to 0 and 1 in image matrix. Values less than ‘Tmin’ are clipped to 0, and values greater than ‘Tmax’ are clipped to 1.
After this ‘im2uint16’ will convert the image matrix to a 16-bit unsigned integer, rescaling and offsetting the image matrix.
The second line of the code will write the matrix ‘IA’ to a graphics file ‘A.tiff’, the third argument to the function ‘imwrite’ that is ‘tiff’ makes sure that the format of the file is .tiff no matter what extension you give in the file name.
Please refer to mat2gray, im2uint16 and imwrite documentation for more information about these functions.
Hope it helps!
