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, each
element of row j would become
? ?? + ? × ? ?? , where k represents columns 1 through the number
of columns in the matrix.
3. Using the functions written for problems 1 and 2 above, write a
function that solves a
system of linear equations or calculates the inverse of a matrix by
Gauss-Jordan elimination.
Your function should accept a matrix as an argument and return a
matrix of the same dimension

MATLAB A square matrix is a matrix that has the same number of rows and columns. Write a function issquare that will receive a matrix as input, and return logical 1 for true if it is a square matrix, or logical 0 for false if it is not. The function should also display a sentence stating whether the inputted matrix is square or not.
Write a function called ArrrayScalarM(...) that multiplies each element of an array by a scalar (constant integer value). The function takes in three arguments: an integer array, the size of the array, and the scalar. Test the function, by calling it from the main program. You can initialize the array as follows: int arrN[10] = {4, 0, 453, 1029, 44, 67, 111, 887, 4003, 1002};

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.
Sodium hydroxide (NaOH) reacts with sulfuric acid (H2S04) yields sodium sulfate (Na2S04) and water according to the following unbalanced equation To balance this equation, we need to find constants (xi, X2, X3, x4) in front of the products and the reactants to get the balanced equation in the form In order to get the values for x1, X2, .., x4, we compare the number of atoms of sodium (Na), oxygen (0), hydrogen (H), and sulfur (S) in the reactants with...
