We have 8*8*96 matrix and we want to convert this matrix into an image. How to convert it?

imwrite(newcolor,'output','bmp'); %we used this function but it went wrong
Error using writebmp (line 27)
Invalid dimensions for X.

You can write a mxnx3 or mxn matrix into image. You have mxnx96 here?

[vasantha malairamar]

then how to convert mxnx96 into mxnx3?

[KSSV]

This can be achieved by using reshape..but unless what result you expect we cannot decide on it.

[vasantha malairamar]

is there any other way to get an image from the matrix?

[KSSV]

imwrite writes the data into image. What is that data 8x8x96? This can be arranged into 32 matrices of each 8x8X3.

[vasantha malairamar]

how can this be done?

[Walter Roberson]

If it has color information then does it currently correspond to 8 x 8 x 3 x 32, or does it correspond to 8 x 8 x 32 x 3 ?

If it is 32 color images then it is probably 8 x 8 x 3 x 32

"is there any other way to get an image from the matrix?"

Not with .bmp file format.

With GIF file format you could use 'writemode', 'append' to create an animated GIF

With TIFF file format, you can use 'writemode', 'append' to add a "page" to the TIFF file. However, for TIFF files and multiple images I recommend the more detailed controls of using Tiff objects.

For any of the other image types you have two options:

1. Write out a series of images with related names, such as output001.bmp output002.bmp and so on; or
2. reshape to 8 by (8 times 96) -- a short and wide series of images side by side.

You also have the option of writing a 3D volume with dicomwrite(), or of writing a multiband data file https://www.mathworks.com/help/matlab/ref/multibandwrite.html

Oh yes, there are also ways to write each image as a "page" in a PDF file. Which really seems a waste for 8 x 8 images.
