1) Suppose i have a (8x8) matrix and i want this matrix to be converted into image (as shown in below image).
Note that each row of the matrix correspond to the each row of color in the image.
2) Also if i have R,G,B matrix, then how can i create the image (as shown in below image)

HEMRAJ thanks for your help. I am able to create image. But the image is too small and only a single strip . I want to create strips of color equivalent to my input no. Below is my code which i used.
Matrix1 =[0 0 0]
Matrix2 =[1 1 1]
Matrix3 =[0 0 0]
[m,n]=size(Matrix1);
my_image=[m,n,3];
my_image(:,:,1)=Matrix1;
my_image(:,:,2)=Matrix2;
my_image(:,:,3)=Matrix3;
imshow(my_image);
Please suggest how i can create image like this
Please note color may vary this is only example of image

Thank U all for your help. I am now able to create image using RGB values. But how can i directly give input of R,G,B values in uint8 instead of double.

Using:
imwrite(A,'Image.jpg')
where A is a matrix 3D, A(:,:,1) = Red channel, A(:,:,2) = Green Channel, A(:,:,3) = Blue Channel;
