You can sample the matrix with higher Frequency rate or use the following technique :

 imshow(M,'notruesize');

Using the higher sample rate :

 G=upsample(M,2); %  doubling the rate for M
 G=upsample(G',2);

Thank You but i dont understand it. Can you please elaborate it. i should use imagesc?

[Youssef Khmou]

the matrix has small size , then it can not be displayed properly, to overcome this issue, you can resample it with higher rate to have higher dimensions, replace 2 with 4 or 5 to test the result.
