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);

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.
