Measuring the frame dimensions of a vehicle is an important part of maintaining its safety and performance. Knowing the exact measurements of your vehicle’s frame can help you make sure that it is in good condition and that all components a...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. The size of this dimension becomes 1, while the sizes of all other dimensions remain the same. B = all( A , 'all' ) tests over all elements of A . This syntax is valid for MATLAB ® versions R2018b and later.Syntax d = size (X) [m,n] = size (X) m = size (X, dim) [d1,d2,d3,...,dn] = size (X) Description d = size (X) returns the sizes of each dimension of array X in a vector d with ndims (X) elements. [m,n] = size (X) returns the size of matrix X in separate variables and n. m = size (X,dim) returns the size of the dimension of specified by scalar dim.Description. M = max (A) returns the maximum elements of an array. If A is a matrix, then max (A) is a row vector containing the maximum value of each column of A. If A is a multidimensional array, then max (A) operates along the first dimension of A whose size is greater than 1, treating the elements as vectors.

When you use [] to automatically calculate a dimension size, the dimensions that you do explicitly specify must divide evenly into the number of elements in the input matrix, numel(A). Beyond the second dimension, the output, B, does not reflect trailing dimensions with a size of 1. For example, reshape(A,3,2,1,1) produces a 3-by-2 matrix.
