Multidimensional Arrays
Every array in MATLAB has trailing dimensions of size 1. For multidimensional arrays, this means
that a 3-by-4 matrix is the same as a matrix of size 3-by-4-by-1-by-1-by-1. Examples of
multidimensional arrays with compatible sizes are:
• One input is a matrix, and the other is a 3-D array with the same number of rows and columns.
• One input is a matrix, and the other is a 3-D array. The dimensions are all either the same or one
of them is 1.
Empty Arrays
The rules are the same for empty arrays or arrays that have a dimension size of zero. The size of the
dimension that is not equal to 1 determines the size of the output. This means that dimensions with a
