size
sz = size(A) returns a row vector whose elements are the lengths of the corresponding dimensions of A
- For example, if A is a 3-by-4 matrix, then
size(A) = [3 4]
- For an empty array, vector, or scalar,
size still returns a two-element vector
- If A is a table or timetable,
size(A) returns a two-element row vector consisting of the number of rows and the number of table variables !tocheck
szdim = size(A,dim) returns the length of dimension dim when dim is a positive integer scalarszdim = size(A,[dim1,dim2,…,dimN]) returns the lengths of dimensions dim1, dim2, …, dimN as a row vector szdim
- The brackets
[] may be omitted
[sz1,...,szN] = size(__)
- The argument may take any of the three forms above
- For the second and third forms, the number of outputs on the LHS must match the number of dimensions queried
- For the first form, when A has more than N dimensions, szN is the product of the lengths of the remaining dimensions
