str = string(A) str = "Four score and seven years ago" strcontains the same characters asA. But whileAis a character vector,stris a string scalar. c = size(A) c =1×21 30 s = size(str) s =1×21 1 To return the number of characters instr, use thestrlengthfunction. ...
Create a string array that contains addresses. Get str = ["221B Baker St.","Tour Eiffel Champ de Mars","4059 Mt Lee Dr."] str = 1×3 string "221B Baker St." "Tour Eiffel Champ de Mars" "4059 Mt Lee Dr." To find addresses that contain numbers, create a pattern that matches...

Create a string that includes a phone number. str ="Hide the numbers in: (508) 555-1234" str = "Hide the numbers in: (508) 555-1234" Create a pattern that matches a digit using thedigitsPatternfunction. pat = digitsPattern(1) ...
This function finds edges using the Prewitt approximation to the % derivatives with the assumption that input image values outside the bounds % are zero and all calculations are done using double-precision floating % point. The function returns g with size mxn. The image g contains edges at %...
