Solutions ChE132B HW1 20pt Problem 1 part (a) 3pt The values of pi, i, and j are 3.14159…, , and , respectively as shown by the MATLAB Input/Output below: >> pi ans = 3.1416 >> i ans = 0 + 1.0000i >> j ans = 0 + 1.0000i If any of these constants, pi, i, or j are redefined in the Command Window, then their value is whatever has been assigned. However, even if their values have been redefined in the Command Window, their values remain 3.14159…, , and , respectively, in an M-file so that you do not have to worry about the M- file not working as designed because one or more of the constants pi, i, or j have been redefined in the Command Window. You can demonstrate this by running the following M-file (test.m) after you have redefined any or all of the constants, pi, i, or j: function[]=test() x=pi y=i z=j
