In MATLAB Command Window and using format short, do the following in sequence. The output of each command must be displayed in the Command Window. Create the matrix M using the MATLAB reshape0 function as >> M = reshape (21:50 , 5,6) a. Delete column 3 of M. b. Display the element in row number 4 and column number 3 of matrix M. c. Create a subarray M1 that consists of columns 1,2 and 5 of matrix M. d. Create a subarray M2 that consists of rows 1,3 and 5 of matrix M. e. Create a 6x5 matrix M3 of the rows of M2 followed by the transpose of M1. Use a suitable MATLAB built-in function in a single command to determine the dimensions of M1 and to assign the number of rows to variable r1 and the number of columns to a variable c1. f
