Do the commands in MATLAB, then copy the code into an editor for your report, put in some comments as to what the effect of the computation is. One way to present your work could be input, output, and explanation. (a) Open a MATLAB window. In it type each of the following commands; when you have typed a command press 'enter'. a=172.5a3b=exp(4)pic=b/a When you have done this enter the command a=b+16 pi. What is the value of a now
