Write and upload a MATLAB script to do the following.

Compute the sequence S(n+1) = (2 – K) S(n) – S(n-1) ;   Assume S(1) = 0, S(2) = 1;

(a)    Case 1, Assume K = 1

(b)    Case 2, Assume K = 2

(c)     Case 3, Assume K = 4

Plot all of these on the same plot, for N = 1 to 20

Using MATLAB or Octave, use documenting code to Write a script that prompts the user for an integer between 0 and 9999, inclusive. The script should then calculate the digit in each of the 1000’s, 100’s, 10’s, and 1’s place of the number. Create a variable for each of the 4 extracted digits. For example, if your variables are named nThousands, nHundreds, nTens, and nOnes, then, in the case of 9471, they would be end up being set to 9,...

Write a Matlab script that plots the following functions over 0 ≤ x ≤ 5π: f1(x) = sin2 x − cos x, f2(x) = −0.1 x 3 + 2 x 2 + 10, f3(x) = e −x/π , f4(x) = sin(x) ln(x + 1). The plots should be in four separate frames, but all four frames should be in one figure window. To do this you can use the subplot command to create 2 × 2 subfigures.
