Create two strings. Get str1 = "Good"; str2 = "Morning"; Combine them using the append function. Get str = append(str1,str2) str = "GoodMorning" To add a space between the input strings, specify a space character as another input argument. Get str = append(str1,' ',str2...
Add Scalar to Array Create an array,A, and add a scalar value to it. A = [0 1; 1 0]; C = A + 2 C =2×22 3 3 2 The scalar value is added to each entry ofA. Append Strings Create two 1-by-3 string arrays, then append similarly located strings in the arrays. ...
