You can specify the day of the week either by number or by name. For example, you can specify Monday …Initializing a Nonempty Array. To initialize a nonempty array, use a function such as zeros or ones to fill the array with initial values. MATLAB does not have a null value, so all nonempty arrays must have values for all elements. You cannot use empty to create a 3-by-3 array, for example, because at least one dimension must have length 0. This MATLAB function returns a row vector whose elements are the lengths of the corresponding dimensions of A. ... Create a random 4-D array and return its size ... 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.You can use MATLAB functions such as randn, ones, and zeros to generate multidimensional arrays in the same way you use them for two-dimensional arrays. Each argument you supply represents the size of the corresponding dimension in the resulting array. For example, to create a 4-by-3-by-2 array of normally distributed random numbers. B = randn ...The general pattern is. [ start : step : stop ]; So if you want only even numbers from 2 to 100, you can do.
