I have generated the following matrix:
A =
0 0 0 0 0 2 2 2 0 0 2
0 2 0 2 0 0 0 0 0 2 0
2 2 0 2 2 0 0 2 2 2 2
2 2 0 0 0 2 2 0 2 0 2
2 2 2 0 0 2 2 0 2 0 0
2 2 2 0 2 0 0 2 2 2 0
2 2 2 2 2 2 2 2 2 2 0
2 2 2 0 2 2 2 2 0 2 2
2 0 2 0 2 2 2 2 2 0 0
2 2 2 2 2 2 2 2 0 2 2
How do I only select the zero values in the matrix?

When you say, "only select the zero values", can you be specific about what you want the output to be? Don't just rephrase it as something like, "I only want the zeros". Say exactly what the output should be.

You want the fraction of zeros in the array?
A = ...
[0 0 0 0 0 2 2 2 0 0 2
0 2 0 2 0 0 0 0 0 2 0
2 2 0 2 2 0 0 2 2 2 2
2 2 0 0 0 2 2 0 2 0 2
2 2 2 0 0 2 2 0 2 0 0
2 2 2 0 2 0 0 2 2 2 0
2 2 2 2 2 2 2 2 2 2 0
2 2 2 0 2 2 2 2 0 2 2
2 0 2 0 2 2 2 2 2 0 0
2 2 2 2 2 2 2 2 0 2 2];
mean(A==0,"all")
