29. Write a user-defined MATLAB function that finds the largest element of a matrix. For the function name and arguments, use [Em, rc] = matrix- max (A), where A is any size matrix. The output argument Em is the value of the largest element, and rc is a two-element vector with the address of the largest element (row and column numbers). If there are two, or more, ele- ments that have the maximum value, the output argument rc is a two-col- umn matrix where the rows list the addresses of the elements. Test the function three times. For input create a 4×6 matrix using the following command: x=randi ([-20 100],4,6).

Write the MATLAB commands that assign 33 and 4 to the variables a and b, respectively. Then, create a column vector W with the elements а! In(ab) Vb - a V(a + b)² – (b – a)? -a b where y! is the factorial of y, for which you should use a built-in MATLAB function, and In(x) is the natural logarithm of x. Finally, compute the average of the elements in W.
Write a driver function which initializes two rectangular matrices and multiplies them together. Remember that two matrices can be multiplied only if the number of columns of the first matrix is equal to the number of rows of the second matrix (i.e. A[n,m] X B[m,p] = C[n,p]).
Write MATLAB expression to do the following: A. Evaluate the maximum value in the vector resulting from element-by-element multiplication of the second column of B with the 1st column of A. B. Use element-by-element division to divide the 1st row of A by the 1st three elements of the third column of B. evaluate the sum of the elements of the resulting vector.
Use nested loops to rewrite MATLAB's min() function. Your function should be capable of either taking in a vector or a matrix as an input argument. If the argument is a vector, your function should calculate the smallest value in the vector. If the input argument is a matrix, your function should calculate the smallest value in each column of the matrix and return a row vector containing the smallest values.
Write a MATLAB function (testLucky.m) that takes a number as an input argument and checks to see if the number is lucky. In the function, begin by defining a vector named secretLucky with the values 19, 22, 5, 9, 11, 15, 21. These are secret lucky numbers. Use a for-loop in the function to check, element-by-element, if the number passed in to the function is in the secretLucky vector. If the number is found in secretLucky, return true (1). If the number is not found in secretLucky, return false (0). Include help comments in the function. Your testLucky function must behave as shown below: (user input is underlined) » help testlucky testlucky(x) - determine whether x is a lucky number return true (1) if x is a lucky number return false (0) if x is not a lucky number Author: your_name » testlucky(5) ans = logical » testlucky(6) ans - logical Hint: To get a logical 1 and logical 0 as output of your function, see "help true" and "help false".

Write a procedure called STRUCTURE-TO-MATRIX that takes an adjacency structure as its only parameter, and returns an equivalent adjacency matrix. Assume there is a procedure MAKE-MATRIX(m, n) that returns an m × n integer matrix, where m ≥ 0 and n ≥ 0. The integers in this matrix are undefined.
just need an expert approach to thus problem to compare with mine Write a MATLAB user-defined function y = MySort(x,Type): x is a vector containing numbers, and Type can be ‘Ascending’ or ‘Descending’. This function should sort the given vector x in the ascending or descending order based on the user’s request and return the desired vector as the output. Do not use MATLAB built-in function sort. Hint: When you call this function, you need to use ‘’ for Ascending or Descending since they are strings.
2. Show that matrix multiplication distributes over matrix addition: show A(B + C) = AB+ AC assuming that A, B, and C are matrices of compatible size. 3. Write a function my_is_orthogonal (v1,v2,tol) where v1 and v2 are column vectors of the same size, and tol is a scalar value strictly larger than zero. The output should be 1 if the angle between vl and v2 is within tol of 1/2, that is, |7/2 – 0| < tol, and zero otherwise. You may assume that vl and v2 are column vectors of the same size, and that tol is a positive scalar.
