Write a function named Prodstate that will accept a matrix Prodstate that has at least one row and at least two columns. The rows each represent a different machine in a factory and the columns represent successive days of production. The value in each element is the number of units produced by that machine on the given day.
Prodstate should return a new matrix Trend with the same dimensions as prodstate and a row
Each element of Trend indicates whether that day’s production for that machine was less than, equal to or greater than the previous day’s production for that machine. Since the first day (first column) does not have previous data upon which to base the comparison, the first column of Trend will arbitrarily be set to all zeros. All other elements will be set to either -1 (lower production that previous day), 0 (equal production to previous day), or 1 (higher production than previous day).
The first element of Trendrum contains the total number of days that production decreased (In other words, the number of negative ones in Trend), the second element of Trendrum contains the number of days with no change in production (zero in Trend, not counting the zeros on the first day), and the thirds element contains the number of days with higher production (ones in Trend).

- Please help, this for Matlab the image is the first question with following 2 and 3 they go together. 2. Solving the question by using bisection.m with the stopping criterion at 1%. Report the root and # of iterations. 3. by using newton-Raphson matlab script with the stopping criterion at 0.1%. Report the root and # of iterations.arrow_forwardThe title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…arrow_forwardWe have designed a divide-and-conquer algorithm that runs on an input of size n. This algorithm works by spending O(1) time splitting the problem in half, then does a recursive call on each half, then spends O(n2 ) time combining the solutions to the recursive calls. On small inputs, the algorithm takes a constant amount of time. We want to see how long this algorithm takes, in terms of n to perform the task. (a) First, write a recurrence relation that corresponds to the time-complexity of the above divide and conquer algorithm. (b) Then, solve the relation to come with the worst-case time taken for the algorithm. Please show all work in depth.arrow_forward

It also needs to calculate the number of pixels/percentage of the pixels that are in the weeds. Please provide notes in the lines as well so it is easy to follow and understand. Thank you for your help!arrow_forwardYou are the mechatronics engineer of a manufacturing plant. You decide to perform an analysis on a robot arm of the assembly line with the objective of optimizing its performance. After taking several readings of the speed of the arm’s end effector, you approximate its velocity to the function given below. v(t) = -t4 + 5t3 - 7t2 + 3t + 0.22 0 =< t =< 3 where the velocity is in ms-1 Use your knowledge of differentiation to sketch the velocity-time graph, clearly marking the critical points. Using the graph sketched in (a) above, estimate the velocity when t = 1.5 s Calculate the velocity of the function when t = 1.5 s by substituting to the velocity function. Compare this value to the value you estimated in b above.arrow_forward
