Hi Bidlee Devi,
I understand that you have an 8-by-8 matrix of pixel values for an image, and you wish to convert the matrix values into a greyscale image.
This can be achieved using the mat2gray function. You will need to store the grey values in a matrix in MATLAB and then use the following command to obtain the required greyscale image.
I = mat2gray(A)
Where A is the matrix containing pixel values of image.
You can refer the following link for more information.
Convert matrix to grayscale image - MATLAB mat2gray (mathworks.com)
