Use Matlab and write entier script

Problem 2.

Generate the estimate (linear estimate) for y_est, and plot(x , y_est).

Use “hold on” and plot(x,y) and plot(x,y_est), so that you can see the result of the line and how it fits the data. Does it look like it did a pretty good job?

An estimate of the “residual error” is the sum of the squares of the difference between y and y_est.

This is often denoted as r2.

r2 = sum( (y – y_est) .^2)

or equivalently

r2 = sum( (y – y_est)’ * (y – y_est)’)

What is the residual error for the above problem?

Expert Solution

I didn't have data so I am taking arbitrary data. You can try it with the exact data.

Please do rate me and mention doubts, if any, in the comments section.

2. Vector Element Calculation Write a MATLAB script which will randomly generate a 20-element vector with integer values ranging between −100 to +100. Using LOOP command, determine the number of negative elements in the vector. For example, given A = [15 −6 0 -8 −2 5 4 −10 -3 −5], the number of negative numbers are 6.

Use Matlab and write entier script Problem 1. Using the information above, find y(n) for all n between 1:N. y(tn)=mx(tn)+b+r(tn) y=mx+b Plot the points on a graph, without connecting them with a line. Use a command like: plot( x, y, ‘.r’ ) Now we want to find the “best fit” solution. As was mentioned before, this was defined in the prior exercise. (You may wish to read this to understand how the algorithm works.) Use the MATLAB code below. You...

Use MATLAB to create a script which solves for problem 5.9 in the book (5.11 in the 4th edition). Given are the equations for the moment, as a function of x, starting from the leftmost side of the beam with x=0 and ending at the other end of the beam with x=12. This piecewise function together makes up the moment equation for the beam given. 0 ≤ ? ≤ 3 ?(?) = 265? − 5.56?3 , 3 < ? ≤...

MATLAB: Write as a script in the editor window of matlab. Quadratic roots. Write a program, quadroots.m, for finding the roots of the second- order polynomial ax2 + bx + c. Use the quadratic equation. The inputs are the coefficients a,b, and c and the outputs are z1 and z2. The program should produce (exactly) the following output in the Command window when run with (a, b, c) = (1, 2, −3):

Using MATLAB or Octave, use documenting code to Write a script that prompts the user for a minimum and maximum real number, then generates and prints a random number in the requested range. The script should then do the same for an integer range. Sample output: Enter a minimum real value: 0.5 Enter a maximum real value: 30 A random number in the range ( 0.5000, 30.0000 ) is 1.7851 Enter a minimum integer value: -10 Enter a maximum integer...

Write a matlab code for given task Use your ‘sin’ or ‘cos’ function to generate a sinusoid wave having two components as f1 = 3kHz and f2 = 5kHz and then sample it with fs = 10kHz. Calculate its fft with zero frequency component in the middle. Plot it on a properly scaled w-axis. Specify if there is aliasing or not? If there is aliasing specify which component is casing the aliasing
