write a function that takes as input a matrix A and ohtputs a matrix B. The entry in the jth row and the ith column of B should be the element from the ith row and jth column of A. Do not use any built in functions. Test the function with the matrix. A=[ 1,2,3,4;4,3,2,1;-1,0,1,0]

In matlab notation.

Answer #1 
A=[ 1,2,3,4;4,3,2,1;-1,0,1,0]
[r,c] = size(A);
B = zeros(c,r);
i = 1;
j = 1;
while i<=r
    j = 1;
    while j<=c
        B(j,i) = A(i,j);
        j = j + 1;
    end
    i = i + 1;
end
B

    What would the function look like in MATLAB? Write a function called mysort that takes a 3-element vector as its sole arguments. It uses if statements, possibly nested, to return a 3-element vector with its elements in non-decreasing order, i.e., the first element in the returned vector equals the smallest element of the input vector and the last element equals the largest element in the input vector. NOTE: Your function should not use any built-in functions, e.g., sort, min, max,...

    2. Matrix A = Matrix B = log(A) Write MATLAB expressions to do the following. Evaluate the sum of the first row of B Evaluate the maximum value in the vector resulting from element-by-element multiplication of the first column of B with the third column of A. Use element-by-element division to divide the third row of A by the first three elements of the second column of B and evaluate the sum of the elements of the resulting vector.

    Matlab: Write a function called minimax that takes M, a matrix input argument and returns mmr, a row vector containing the absolute values of the difference between the maximum and minimum valued elements in each row. As a second output argument called mmm, it provides the difference between the maximum and minimum element in the entire matrix. See the code below for an example: >> A = randi(100,3,4) A = 66 94 75 18 4 68 40 71 85 76...

    *** Write a function called reverse_diag that creates a square matrix whose elements are 0 except for 1s on the reverse diagonal from top right to bottom left. The reverse diagonal of an nby- n matrix consists of the elements at the following indexes: (1, n), (2, n-1), (3, n-2), … (n, 1). The function takes one positive integer input argument named n, which is the size of the matrix, and returns the matrix itself as an output argument. Note...

    Write a function called ''minandmax'' . Function ''minandmax'' takes only one input argument that is a matrix M . This matrix M can be any size (any number of columns and rows) with any random integer values . Function ''minandmax'' returns two output arguments. The first output argument is called ''difference_row'' that returns a row vector containing the absolute values of the difference between the maximum and minimum valued elements in each row. The second output argument is called ''difference_all''...
