Math lab code please

load -mat x.dat would treat file x.dat as a MAT-file even though its file extent is not .mat. Similarly, the load statement can be forced to treat a file as an ASClIl file by specifying the -ascii option. These options allow the user to load a file prop- erly even if its file extent doesn't match the MATLAB conventions. Quiz 2.3 This quiz provides a quick check to see if you have understood the con- cepts introduced in Sections 2.6 and 2.7. If you have trouble with the quiz, reread the sections, ask your instructor, or discuss the material with a fel- low student. The answers to this quiz are found in the back of the book. 1. How would you tell MATLAB to display all real values in exponen- tial format with 15 significant digits? 2. What do the following sets of statements do? What is the output from them? (a) radius input ('Enter circle radius:n) area-pi * radius*2; str = [The area is . num2str (area)); disp (str) (b) value int2str (pi) disp(I The value is value 3. What do the following sets of statements do? What is the output from them? value 123.4567e2; fprintf ('value %ein' , value); fprintf ('value- %f ',Value); fprintf ( 'value- tgin, , value) ; fprintf ('value 812.4f1n',value): Scalar and Array Operations
