- Create a row vector of 1's that has 4 rows. Now Create a column vector of 1's that has 4 columns. Using matrix multiplication, multiply both of these to get a 4x4 matrix and display the resulting matrix. Using matlab, do this. Please answer it correctly and don’t copy from anywhere otherwise it will be downvoted.MATLAB: Create a vector named n which starts at -10 and steps by 1 to end at +10 by using the start:step:stop syntax. Next, generate a vector x1 so that x1 satisfies the mathematical relationship ?ଵ[?]=(0.60). Since n is a vector, one will need to utilize 0.60.^n (i.e., .^ is used in place of ^) to define x1. Redo the work just completed, but for a vector x2 where x2 satisfies the mathematical relationship ?ଶ[?]=(0.85). Repeat the work just completed, but for a vector x3 where x3 satisfies the mathematical relationship ?ଷ[?]=(1.10). In one figure window, plot x1 as a function of n using the stem command. The stem plot must show BLACK (versus the default blue) lines that have filled circles and a line width of 2; refer to the lecture example script file. Further, the horizontal axis label (xlabel) must be n, the title (title) must include your name and the vertical axis label (ylabel) must show ?ଵ[?]=(0.60)(note the subscript and superscript). In addition, turn on the grid (doc grid),…Write a program in Fortran language to read and print the matrix A(5,3) and then the program does the following: Arrange the elements of the first column in descending order if the number of negative elements in this column is greater than the number of positive elements and print the resulting matrix
- %In this activity you will learn how to define matrices, use the size() command to find the size %of a matrix, generate an identity matrix, and also compute the transpose of a matrix using %the " .' " operator. %Matrices in Matlab can be constructed by entering each row of values. %Rows are separated from each other using a semicolon. %For example, consider the 2x4 matrix B defined as: B = [1 2 3 4; 5 6 7 8] %The size() function can be used to compute the number of rows and columns of a matrix. %Compute the number of rows and columns of B by using the size() function and store these values. [numRowsTest,numColsTest] = size(B) %The eye() function can be used to create an n by n identity matrix. %Create the 3x3 identity matrix and store it as I. I = eye(3) %The "dot-tic" operator can be used to transpose a matrix. %Take the transpose of the matrix B and store it as the matrix C. C = B.' ------------------------------------------------------------------------------- Question:…What are the most significant advantages of arrays, in your opinion? This is the utmost number of dimensions a matrix can contain. The following describes the distinction between a structure and an ordinary variable type: Use a complex data structure to illustrate its utility.The conversion from feet to meters is: meters = feet × 0.3048 Create a MATLAB program that creates a vector called feet that starts at 0, increments by 0.01, and ends at 10. Have the program convert the feet vector to a meter vector and then create a matrix of outputs with feet in the first column and meters in the 2nd column. All values should contain exactly 4 decimal places. Include your answers in comments using %.
