2.21 Create a matrix called D_ to R composed of two columns, one represent ing degrees and the other representing the corresponding value in radi- ans. Any value set will do for this exercise. . Save the matrix to a file called degrees.dat. Once the file is saved, clear your workspace and then load the data from the file back into MATLAB For this question, in addition to saving D to Rto a file called degrees.dat and loading it back as requested in the book, save the same matrix to another file degrees.mat and load it back
