Webbsizeof can be used to determine the number of elements in an array, by dividing the size of the entire array by the size of a single element. This should be used with caution; When passing an array to another function, it will "decay" to a pointer type. At this point, sizeof will return the size of the pointer, not the total size of the array. Webbsz = 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) returns the vector [3 4]. If A is a table or timetable, then size (A) returns a two-element row vector consisting of the number of rows and the number of table variables. example
