HOMEWORK for LAB 7 a) An exponentially damped sinusoidal signal is defined by x(t) = 20sin(2π × 1000t − π/3)(e −at) where the exponential parameter a is variable, taking on the set of values a=250, 500, 750, 1000. For each a value draw x(t) signal for −2 ≤ t ≤ 2 miliseconds. Observe the effects of a on the signal. Using subplot command plot x(t) signals for all a values on the same graph. b) Please wrie a MATLAB fprogram that assigns a set of numbers to an array then using a function "called rotate and written by you too" to rotate the array. The program will display evey step on the screen at each second as ; 123456 -> 612345 -> 561234 ->4561234->345612 -> 234561 -> 123456 |

Usage of functions calling other functions and passing arrays between functions. Debugging and troubleshooting in Matlab Programs
LECTURE 7 :
a) Finding the perfect numbers up to the given numbers. (Perfect number is a positive integer that is equal to the sum of its propoer positive divisors, that is, the sum of its positive divisors excluding the number itself.) b) Finding the subtraction of the sum of the odd numbers in an array from the numbers at the even indexes in the same array.
|
HOMEWORK for LAB 8 Create a vector which is composed of 100 random integers from 1 to 99. By creating a matrix, place each element to different rows one by one according to the ranges. There will be 10 different ranges (1-9, 9-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89, 90-99). Finally, count the number of values belonging to each range by using another vector that has all ones initially. |

HOMEWORK for LAB 9 Take a value called "n" from the user, then Create two arrays with size floor(n/2) called arrayodd and arrayeven and fill them with random odd / even numbers between 1-100. Then store them into another array called arrayone such that; 1.st element of arrayone will be the first of arrayodd, 2.nd element of arrayone will be the first of arrayeven + first of arrayone, 3.rd element will be the second of arrayodd + first 2 elemets of arrayone and goes like this

Plotting, and some plotting properties of Matlab (Plot, subplot, stem, title, axis, legend, set, fill, grid, hold,…)
LECTURE 9 : a) Write a MATLAB program that creates 2 arrays each of whih is filled by 5 random numbers. Then creates a 3rd array on which the array elements of other 2 arrays are taken 1 by 1 and added to previous item of 3rd array before appending it to the 3rd array & Midterm Solutions b) Write a MATLAB program that generates 100 random numbers between 1 and 100. THen stores them to an array for which the elemnts vith value in 0-10 range willbe stored n 1st row of the array, 10-20 range willbe stored n 2ndrow of the array etc. finaly displays the number elemets in each row seperately c) do the samething by animating while loacting the values into the array and at the end the results will be platted.

HOMEWORK for LAB 10 Write a program to find the number of days between 2 dates. User will enter 2 different dates where the first one should be older than the second one. This program should take into account the leap year (366 days in a year, occurs every 4 years period) as well as the number of days between months. There will be two different scenarios depending on whether or not the first month is smaller or larger than the second month. |

Some built in functions, (int, trapz, diff, rand, mod, zeros, find, exp …), their usage methods and examples LECTURE 10 : Write a program in which there will be n elements (the n value will be taken from the user) which will be shown by red diomonds and they will move in an area of 100x100 with random speeds and to random directions. they will also reflect when they hit to the borders or to eachother |
HOMEWORK for LAB 11 Each new term in the Fibonacci sequence is the summation of the previous two terms. The first 10 Fibonacci sequence terms are as follows: Write a Matlab code; a) that finds the summation of both the even-valued terms and the odd-valued terms separately for the first 10 terms. This program should also count the total number of even-valued terms and the total number of odd-valued terms. b) that finds the summation of both the even-valued terms and the odd-valued terms separately, where the term values do not exceed 2000. This program should also count the total number of even-valued terms and the total number of odd-valued terms. |

Developing Matlab programs including “Mobile objects” for simulation purpose
LECTURE 11 : Write a program in which there will be n elements (the n value will be taken from the user) which will be shown by red diomonds and they will move in an area of 100x100 with random speeds and to random directions. they will also reflect when they hit to the borders or to eachother |
HOMEWORK for LAB 12 Write a Matlab program for the following dice game: A player rolls two dice. Each die has six faces. These faces contain 1, 2, 3, 4, 5 and 6. For each roll, the sum of the two upward faces is calculated. Case1) If the sum is 7 or 11 on the first throw, the player wins. Case2) If the sum is 2, 3 or 12 on the first throw, the player loses. Case3) If the sum is 4, 5, 6, 8, 9 or 10 on the first throw, the sum becomes the player's point. In order to win, player must continue rolling two dice until the new sum will equal to the player's point. In that case, you should count how many times the roll has thrown to reach the point. |

Create a N-valued vector which includes only even and non-recurring random numbers ranging in between 27 to 63. For each number in the array, calculate the absolute difference from the ones digit value and the tens digit value. If this difference is smaller than 5, then place this number into another array. Finally, display this final array on the screen. c) Write a program to reverse the digits of the given number. d) Store the numbers from 1 to 1000 to the following arrays -1st array includes non-prime and non-perfect numbers -2nd array includes non-prime and perfect numbers -3rd array includes prime and non-perfect numbers -4th array includes prime and perfect numbers |
