I need only #25 solution using MATLAB

23. Use a text editor to create a le containing the following data. Then use the load function to load the le into MA TLAB, and use the mean func- tion to compute the mean value of each column 49 63 58 42 39 51 45 98 95 92 90 24. Enter and save the data given in Problem 23 in a spreadsheet. Then im port the spreadsheet le into the MA TLAB variable A. Use MATLAB to compute the sum of each column 25. Use a text editor to create a le from the data given in Problem 23, but separate each number with a semicolon. Then use the Import Wizard to load and save the data in the MATLAB variable A
