See the documentation on the im2bw (link) and imbinarize (link) functions.

I need grayscale image to be an 8 by 8 binary matrix.

See the documentation on Matrix Indexing (link).

After thresholding with the functions, or yourself like this:

binaryImage = grayImage > someThreshold;

call imresize() to make the image 8 by 8

binaryImage = imresize(binaryImage, [8,8], 'nearest');

Search the File Exchange (link) for Image Analyst’s demonstrations.

Experiment with your image to get the result you want. See the documentation for the functions we referenced.
