I have decomposed sentinel-1 SLC image. The result gave the Entropy image whose pixel value ranges from 0 to 1(image has only one band). the image is converted to .tiff file. and imported to Matlab. the image array is showing values in the grey scale i.e. 0-255, But the band having entropy value is also showing same values in gray scale. How to get entropy values from the image which is in the range(0-1).
the code i have followed as follows
[entropy, R] = readgeoraster("subset_2_of_S1A_IW_SLC__1SDV_20211028T004043_20211028T004110_040312_04C6EF_A357_Spk_Decomp_TC_Cnv.tif");
info = geotiffinfo("subset_2_of_S1A_IW_SLC__1SDV_20211028T004043_20211028T004110_040312_04C6EF_A357_Spk_Decomp_TC_Cnv.tif");
Entropy_val = entropy(:,:,1);

yes,sir,may be use
entropy = mat2gray(entropy);

yes,sir,as up friend suggest,use im2doule、double(matrix)/255 can get double value
