- For grayscale images, A can be m-by-n.
- For indexed images, A can be m-by-n. Specify the associated colormap in the map input argument.
- For truecolor images, A must be m-by-n-by-3. imwrite does not support writing RGB images to GIF files.

Hi all,
I am currently working on a 3D matrix contains 220 different values from 0-1 with Double format. The scale of this matrix is 2520*2520*1804. Now I want to convert this into a 3D Tiff file using imwrite function and it turns out the file is too big. I would much appreciate if anyone could give me some possible solutions on regard this issue. Thank you very much for your time.
Cheers,
Quan

A — Image data
matrix
Image data, specified as a full (nonsparse) matrix.
For TIFF files, A can be an m-by-n-by-4 array containing color data that uses the CMYK color space.
You are trying to write m = 2520 n = 2520 ... by something that is not 3 or 4. imwrite() cannot do handle it.
What you can do is imwrite() one layer at a time, with "writemode", "append". The result will, however, not be a 3D Tiff file.
In order to get a 3D tiff file. you need to use the Tiff() class, and you have to write special tags.
Unfortunately there is no tiff write volume corresponding to tiffreadVolume
