(Calculator Using Function Pointers)
Using the techniques you learned in Fig. 7.28, create a text-based, menu-driven program that
allows the user to choose whether to add, subtract, multiply or divide two numbers. The
program should then input two double values from the user, perform the appropriate
calculation and display the result. Use an array of function pointers in which each pointer
represents a function that returns void and receives two double parameters. The corresponding
functions should each display messages indicating which calculation was performed, the values
of the parameters and the result of the calculation. In both cases, display the value to 2
digits of precision.
Note: do not accept invalid menu selections, print an error message and ask the user to try
again. Furthermore, if the user chooses division but enters 0 as the divisor, do not accept the
entry, print an error message and ask the user to enter another number instead.

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata. mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata. mat g(s) = a1/(s + a2)
