回答： Paul Hoffrichter 2020-11-27

B = [1 2 3; 4 5 6; 7 8 9];
size(B)      % ans = 3     3
biterr(B,B)  % ans = 0

Why does biterr work here, but not below?

A = B;
A(:,:,2) = [10 11 12; 13 14 15; 16 17 18];
size(A)      % ans = 3     3     2
biterr(A,A)
Operands to the || and && operators must be convertible to logical scalar values.
Error in biterr (line 212)
if aIsNumeric && (num_bits > 1)

Hi Paul

As mentioned in the biterr documentation, the inputs must be either a vector or a matrix with mxn dimensions. 3D matrices are not supported as of now. I have brought this issue to the concerned people and it might be considered in any future release.

Hope this helps

Maybe I am not looking hard enough.

>> the inputs must be either a vector or a matrix with mxn dimensions

Only thing I saw in the documentation is " if the matrix has dimensions m-by-n," and that was for the special cases where one of the inputs is a matrix and the other input is a row or col vector.
