I need matlab code.

You do not need to use the 4 step method on this problem. A. Create a variable containing a one row character array containing some letters'. Do this using square brackets and individual characters. Use class to confirm the type of the variable. B. Repeat the last part but create the string variable using a single set of single quotes. C. Make a two row character array containing some' and 'letters' on separate rows. What do we need to do to make sure these two words can be fitted into a two row array? D. Make an explicit conversion of the character array from the last part to a numeric type. E. What happens if we try to make an explicit conversion of the character array of the last part to a logical type? F. Make an implicit conversion of the character array to a numeric type. G. For each of the following string, try and generate a corresponding numeric value using the str2double function. Give the reason why some of these conversions can fail and how we can test for it. 1-4 'j' 2.5' x.97 13.7e+041
