Transcribed Image Text:Problem 1/MatlabGrader (20 points) (Core Course Outcome 4)
Develop a Matlab function myFitExam that finds the best fit of the function
p(t) = as
sin³ (t) + b sin² (t) + csin(t) + d
(1)
to a given set of data points (ti, pi) using regression. Here t is in radians.
The function input shall be
⚫t: column vector of data values t
⚫ p: column vector of data values p
The function output shall be
• a: scalar containing the best fit coefficient a
b: scalar containing the best fit coefficient b
c: scalar containing the best fit coefficient c
d: scalar containing the best fit coefficient d
In the function use only functions developed in this class in modules 1 - 4. You do not need to provide these functions in your
submission. They will be provided when assessing your function after the deadline.
Note: no assessments will be performed on your submitted function before the exam deadline. Scores on Canvas for this problem
before the exam has been fully graded are meaningless.
Required submission:
☐ well commented function source code submitted to Matlab Grader using the Canvas link for Exam 4 - Problem 1
Problem 2 (15 points) (Core Course Outcome 4)
Consider the following unsorted table of measured data points (ti, pi):
t 1/4 1 6 5
2
1/2
7/2
р 1/2 1 1
-1
3/2 1
-2/3
Use your function myFit Exam from problem 1 to determine the coefficients a, b, c, and d in p(t), see Eq. (1), that best fit the data.
Print the coefficients with at least 7 significant digitis.
Required submission:
☐ printout of script source code used to solve this problem in your Gradescope submission;
printout of coefficients with at least 7 significant digits in your Gradescope submission;

- In your biomechanical testing lab, you perform a series of compression tests to determine the relationship between apparent bone density (p, units of g/cm³) and ultimate stress (ơult, units of MPa). Using the set of experimental measurements below, write an m-file to fit a power relationship of the form O uli = Ap to the data. Use the log transform method to linearize the system and data, followed by linear regression. Plot the data points and the power relationship on a single plot. Be sure to label your axes and provide a legend. Provide a printout of your m-file and a printout of the command window showing your results.

You do not need to include the M.files for the bisection method (bisect.m) and for false position (falspos.m). You must, however, show the command lines for the given functions with their variables and other parameters. Fanning friction factor For fluid flow in pipes, friction is described by a dimensionless number, the Fanning friction factor f. The Fanning friction factor is dependent on a number of parameters related to the size of the pipe and the fluid, which can all be represented by another dimensionless quantity, the Reynolds number Re. A formula that predicts ƒ given Re is the von Karman equation: 4log₁0 (Re√) - 0.4 = Typical values for the Reynolds number for turbulent flow are 10,000 to 500,000 and for the Fanning friction factor are 0.001 to 0.01.

Can you help fix my code and make sure it works. The error is CVX Warning: Models involving "log" or other functions in the log, exp, and entropy family are solved using an experimental successive approximation method. This method is slower and less reliable than the method CVX employs for other models. Please see the section of the user's guide entitled The successive approximation method for more details about the approach, and for instructions on how to suppress this warning message in the future.Error using .* (line 173)Disciplined convex programming error: Cannot perform the operation:…arrow_forward
