%NDIMS Number of dimensions. % N = NDIMS(X) returns the number of dimensions in the array X. % The number of dimensions in an array is always greater than % or equal to 2. Trailing singleton dimensions are ignored. % Put simply, it is LENGTH(SIZE(X)). % % For Java arrays and Java arrays of arrays, NDIMS always returns 2. % % See also SIZE. % Copyright 1984-2005 The MathWorks, Inc. % Built-in function.
