Write a program that reads a matrix from the keyboard and displays the summations of all its rows on the screen. The size of matrix (i.e. the number of rows and columns) as well as its elements are read from the keyboard. A sample execution of this program is illustrated below: Enter the number of rows of the matrix: 3 Enter the number of columns of the matrix: 4 Enter the element at row 1 and chd umn 1: 1...
Problem 5 Create the following matrix by typing elements explicitly one command. Do not type individual 0 00 0 0 o o 0 0 0 0 0 1 2 3 F=0 01 10 20 0 0 2 8 26 0 0 3 6 32 E 0 045 6 0 0 7 8 9 Problem 6 Create two row vectors: a -4 10 0.5 1.8 -2.3 7, b [0.7 9 -53-0.6 12 (a) Use the two vectors in a MATLAB command...
4. Create a variable N that is a column vector with seven equally spaced elements in which the first element is 44 and the last element is 23. 5. Create the following three row vector: a=[5 8-10 2], b=[4 19 -2 3], and c=[-35 06 1]. a) Use the three vectors in Matalb command to creat 3x5 matrix in which the rows are the vectors c, b and a, respectively. b) Use the three vectors in a Matalb command to...
Question 1: For the plane (2D) truss shown below, evaluate the transformation matrix [T] and the stiffness matrix in the local axis system [KL] of all elements. Use these matrices to evaluate the element stiffness matrix in global axis system [KG] of the members and assembled them to generate the overall stiffness matrix [K of the truss. Modify the stiffness matrix [K] in order to incorporate boundary conditions following the elimination technique of rows and columns. Take E 200 GPa...
If z is a 4 by 4 matrix, what is the result of z[ ,c(1,4)) ? All elements of the first and fourth rows All elements of the first and fourth columns Element at the first row, fourth column The first and fourth elements Element at the fourth row and first column
Row and columns sum Create a java program that: Input: Receive as input in command line the sizes m and n of a two dimensional array Receive as input in command line the minValue and maxValue between which the random numbers will be generated for your two dimensional array Generate: Generate a two-dimensional with numbers between minValue and maxValue (inclusive) with the given size (m x n) Compute: Compute the sum for each row and store the results in a...
R programming 1. Write an assignment statement to complete each of the following without using diff() and sign(): (a) generate a vector of the difference between the ith element and the (i+1)th element in a vector v of integers, where i = 1: length(v), and (b) generate a vector of the sign of each elements in the vector generated in (a) as follows: ‘p’ for positive, ‘n’ for negative. (Use v ⟵ c(1,4,7,2,1) for testing.) 2. Write a function that...
In C++ Design a class to perform various matrix operations. A matrix is a set of numbers arranged in rows and columns. Therefore, every element of a matrix has a row position and a column position. If A is a matrix of five rows and six columns, we say that the matrix A is of the size 5 X 6 and sometimes denote it as Asxc. Clearly, a convenient place to store a matrix is in a two-dimensional array. Two...
The problem demonstrates the use of the random number generator to recover previously generated random numbers Write a function called randi test that takes two scalar positive integer arguments maxi and n, and retums two output arguments: a row vector of n2 elements and and n-by-n matrix. The two output arguments must contain the exact same set of random integers that fall between 1 and maxi Do this using the random number genertor, not by reshaping the data Example n,v-randi...
Can someone help me to solve it by Matlab? 7. Create a 5 row, 8 col matrix called mymat w ith random integers betwee n and including 70 and 90 Create a matrix from mymat called newmat whose entries consist of those entries which are both in the second and third rows, but also in the 4th through 6th columns 8. 9 What command would you type to list just the 4th row, 6th column entry of mymat? 1o.
