New to MATLAB. Need help with this problem.
I've just ignored this 3 problems (out of 9) in my final today and I wonder someone could help me to solve these problems so I can understand how to do it. 1/ Suppose we have a job that will take 20 hours to complete, and requires the use of a special (and expensive!) type of battery. It is known from exhaustive testing that the probability one of these batteries will wear out in (exactly) one hour is 0 .1, in two hours is 0.4, in three hours is 0.3 and in four hours is 0.2. For each 5 =< n =< 20 , let Pn denote the probability that exactly n batteries will be required to finish the job. Write a program that uses simulation to approximate the probabilities Pn . Perform a large number of simulated jobs, each time counting how many batteries were needed to complete the necessary 20 hours of work. Whenever a new battery is required, use a random number to determine how long it will last. Assume that as soon as a battery wears out, it is immediately replaced with a new one. Approximate each Pn as the fraction of trials when exactly n batteries were required to finish the job. 2/ The goal is to write a program that will determine whether or not a given number is prime. Let N and D be positive integers. D is called a divisor of N if there is a positive integer Q such that N = QD. An integer N >= 2 is called a prime number (or simply prime) if it has no divisors other than 1 and N itself. Equivalently, N is prime if it is not the product of two smaller po...

Need matlab help
Hi, I am trying to solve an interesting problem. I have a handheld device that contains a basic 3d accelerometer. I am trying to determine the path that the device moves through the air and the timing associated with the device. Think of the device being moved like a tennis racket or golf club. Normally this would be a simple problem to solve as I have the acceleration data. THe complication is that the device swivels in the persons hand and so i do not really know which direction gravity is acting. I am trying to use Matlab to see if i can figure out the path or the timing (even just timi...

I have the following problems and no idea where to begin: 1) The function takes one string that contains two words separated by a space and returns true if the two words are identical (case sensitive).Otherwise, it should return false. Test Case: out1 = compareTwo('winner winner') out1 -> true 2) The function takes in a string which is a sentence of upper and lower case letters. The function then removes the upper case letters to reveal a secret message. The result should not contain any upper case letters. The result may contain lower case letters, spaces and numbers.

MatLab coding help needed for basic engineering problem
Hiya, i've been trying to figure out a way to create a code to differentiate, integerate and plot the results for a fluid mechanics problem and would really appreciate any sort of help that i can get. The problem's about volume-flow through a pump. What i'm meant to do is make a GUI through GUIDE and have 3 m-files which can load data from 2 excel files. the excel files contain 2 columns of Q(volume flow) and time and numerous rows of values taken at different time intervals. What i'm supposed to do is create three m-files to determine: a. The change of volume flow with respect to time of the fluid in the pump i.e dq/dt. b. The volume of fluid entering the hydraulic circuit / | | Q dt | / (integrate Q with respect to t) c. A function file that determines the difference in the volume of fluid in this system and a similar system without a leak, which means the 2 data sets in the 2 excel files. they have been sampled at different rates so i need to interpolate them as well. And in the end, plot all a, b, and c with respect to time. The problem is, i find the derivative of Q with respect to t throw diff(q)./diff(t)...which ultimately caused the resulting dataset to have one element less than q or t, and thus, i cant plot it against t. how do i add another element to diff(q)./diff(t)? i tried using size(dqdt) = [1001,1] => adding one more element to the set but it doesnt accept it (dqdt is diff(q)./diff(t)). What should i do? i believe this would be fair...

Friends and wormbots: I am looking for some intrepid souls to try out and comment on a perl script I wrote. (What, perl in SAS-L and it's not David Cassell ?)

Help: Need help identifying the cause of this problem....
Hi all, The symptoms: When connected to the internet my desktop runs at 100% cpu usage and 100% network usage. There are no idications of which process is actually using 100% CPU. Whatever is wrong with my desktop is now wrong with my laptop - they both run winxp and are connected to the same router. If I disconnect the router from the cable modem both computers continue to run at 100%/100% - disconnect the network cables - or disable the connection - and the problem goes away. Right now I am writing this on my wife's mac - it is also connected to router but works just fine. There is no burner/storage device attached to this mac so I cannot get the latest spybot/adaware/norton updates. My norton is 3 days old and the adaware/spybot are over a month old - don't detect anything. My first attempt was to completely reformat the desktop; give it a clean slate. However, after reformat the 100%/100% problem continues. (Laptop was not on and not connected to network). What kind of computer virus/trojan/exploit survives a fresh reinstall of the OS?

need help on this problem.
Hello, I have an assignment for school. I'm looking for help and advise on how to solve this. My professor is bad, meaning that she can't explain correctly, her english is bad, and it's one of those people that expect students to know everything. well, this is the problem: On a floor, parallel lines separated of a length L are drawn. When you launch a pen of length L on this floor, the probability that it crosses a line is 2/Pi. Suppose that you have a computer that has 64 processors. Write a program to compute Pi in java for that computer. But run it on your computer. I went to her to explain me certain things I didn't understand. For example, the lines are drawn parallel like this: | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and L is the distance between each line. The pen's width (not the length like she wrote it) is L as well. For the rest, the pen is thrown at random. So for example, the pen can fall diagonally or vertically or horizontally. Does anyone else understand this problem? I don't, that's why I'm asking for help from anyone that might have a clue. Even after I visited her her explainations are bad and don't help at all. I was hoping that someone can help me guess what I need to do, since I have no clue. I already spent 2 days on this and I can't come up with anything. I appreciate anyone reading thi...

Hi there every one I need some help with the following function: function cc = find_cc(n) global nu cc(1)=(-8.*i.*nu1-3.*n.^2-5+4.*i.*nu1.*n-4.*n)./n./(-n-2+4.*i.*nu1); cc(2)=(3.*n.^2+2.*n+4)./n./(-n-2+4.*i.*nu1); cc(3)=-(n-1).*(n+1)./n./(-n-2+4.*i.*nu1); end where \nu is abitrary variable. cc(1), cc(2) and cc(3) are entries of a cc(3,1) matrix.
