WebbGrowing Variable-Size Column Array That is Initialized as Scalar at Run Time In MATLAB execution, if you grow a scalar array by using (end+1) indexing, the array grows along the second dimension and produces a row vector. For example, define the function grow: function z = grow (n, m) n (end+1) = m; z = n; end Call grow with example inputs: WebbMATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the …
