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''...

Assignment: Write a C function that accepts the pointer to a matrix of integer numbers (i.e. a two-dimensional array), number of rows and number of columns as input and prints the matrix after rotating it 90 degrees clockwise. Example: void rotate-matrix (int* matrix, int row, int column) Inputs: row 4, column-6 and the pointer to the matrix below: 2 3 6 5 8 0 Output:

1. Write a MATLAB function that takes a matrix, a row number and
a scalar as
arguments and multiplies each element of the row of the matrix by
the scalar returning the
updated matrix.
2. Write a MATLAB function that takes a matrix, two row numbers and
a scalar as
arguments and returns a matrix with a linear combination of the
rows. For example, if the rows
passed to the function were i and j and the scalar was m,...

Create a matrix with 3 rows and 4 columns. Every element in the first row should be 0, every element in the second row should be 1, and every element in the third row should be 2. But don’t just type out all the numbers. Use some ingenuity. Display the matrix using MATLAB.

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 1 Write your code in the file MatrixOps.java. . Consider the following definitions from matrix algebra: A vector is a one-dimensional set of numbers, such as [42 9 20]. The dot product of two equal-length vectors A and B is computed by multiplying the first entry of A by the first entry of B, the second entry of A by the second entry of B, etc., and then summing these products. For example, the dot product of [42 9...

Write a program mexp that multiplies a square matrix by itself a specified number of times、mexp takes a single argument, which is the path to a file containing a square (k × k) matrix M and a non-negative exponent n. It computes M and prints the result Note that the size of the matrix is not known statically. You ust use malloc to allocate space for the matrix once you obtain its size from the input file. Tocompute M". it...

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...
