D = SIZE(X), for M-by-N matrix X, returns the two-element row vector D = [M,N] containing the number of rows and columns in the matrix. For N-D arrays, SIZE(X) returns a 1-by-N vector of dimension lengths. Trailing singleton dimensions are ignored. [M,N] = SIZE(X) for matrix X, returns the number of rows and columns in X as separate output variables. [M1,M2,M3,...,MN] = SIZE(X) for N>1 returns the sizes of the first N dimensions of the array X. If the number of output arguments N does not equal NDIMS(X), then for: N > NDIMS(X), SIZE returns ones in the "extra" variables, i.e., outputs NDIMS(X)+1 through N. N < NDIMS(X), MN contains the product of the sizes of dimensions N through NDIMS(X). M = SIZE(X,DIM) returns the length of the dimension specified by the scalar DIM. For example, SIZE(X,1) returns the number of rows. If DIM > NDIMS(X), M will be 1. When SIZE is applied to a Java array, the number of rows returned is the length of the Java array and the number of columns is always 1. When SIZE is applied to a Java array of arrays, the result describes only the top level array in the array of arrays. Example: If X = rand(2,3,4); then d = size(X) returns d = [2 3 4] [m1,m2,m3,m4] = size(X) returns m1 = 2, m2 = 3, m3 = 4, m4 = 1 [m,n] = size(X) returns m = 2, n = 12 m2 = size(X,2) returns m2 = 3 See also length, ndims, numel.
