Count occurances on multidimensional matrix with multiple criteia on different dimnesions

I would like to count occurances of >= 90 on page 1 and = 2 on page 2 of a multidimensional matrix where both criteria in the same location need to be met to be true for the following:

A(:,:,1)=

[90 95 90 80

70 90 95 70

60 90 90 60]

A(:,:,2)=

[1 1 1

2 2 2

1 2 1]

The answer for the above example should be 3.

Thank you in advance for any assistance.

Sorry page 2 should be

A(:,:,2)=

[1 1 1 1

2 2 2 2

1 2 1 1]

Thanks!

A = zeros(3,4,2);
A(:,:,1)=...
[90 95 90 80
 70 90 95 70
 60 90 90 60];
A(:,:,2)=...
[1 1 1 1
 2 2 2 2
 1 2 1 1];
occurences = nnz(A(:,:,1)>=90 & A(:,:,2)==2)

occurences = 3

Don't know why A(:,:,1) is 3x4 and A(:,:,2) is 3x3 though.

Thanks!

A(:,:,1) = [    90 95 90 80;...
                70 90 95 70;...
                60 90 90 60;...
                ];
A(:,:,2) = [    1 1 1 1;...
                2 2 2 2;...
                1 2 1 1;...
                ];

B = (A(:,:,1) >= 90) + (A(:,:,2) == 2)

B = 3×4

1 1 1 0 1 2 2 1 0 2 1 0

N = sum(B==2,'all')

N = 3

Thank you for the quick response!
