Task 3) Upload QBb.mat with data x, y, variance in y. Note: variance = 0'2

a) [5 pts] The data fits an equation of the form y = c*sin(a*x)"2*exp(b*x) Write a Chi"2 error function for this equation

b) [10 pts] Using pseudo-code tell me how to determine the coefficients a, b, and c.

[15 pts] Write a program to determine a, b, c, and the Chi"2 error? You may use BruitForce.m as a starting point. Make sure to provide the coefficients and error that you calculated.

d) [5 pts] Plot the data and fit with error bars. C) Task 4) Upload Q3c.mat with data x, y, variance in y.

[10 pts] Interpolate the data with a cubic spline and step size of 0.1. Write down all commands and display the interpolated data set with the original data and errorbars. Task 5) [15 pts] Write a function (function 2 = FindinCommon(x,y) ) that determines whether matrixes

have identical size and whether the elements X“ and Y“ are identical. If the matrixes are different size,

then an error message is produced. The output is a matrix ”2” with identical elements displayed as numbers and non-identical elements written as zeros. 2 5 6 2 2 6

Call your function and show the results when x = 2 2 0 and y = 2 1 1
