MATLAB: Write a function called max_number that takes an at most two-dimensional matrix A as its sole input. The function returns the largest element of A. You are not allowed to use the built-in max function.

Expert Solution

Hey just to make it interesting I will only show you the function of 1-D matrix to determine max element.

It goes like this:

now to work on the 2D array you apply various methods:

1st:

divide the elements of the 2D array into number_of_rows simple 1D arrays.

now you have 3 1d arrays and you apply the max function on each of them to get the max from each as:

maxf(A1)=5

maxf(A2)=6

maxf(A3)=9

create a new 1D matrix with elements maxf(A1),maxf(A2),maxf(A3) and apply maxf on that matrix.

you will get the output as 9.

2nd method:

In this case you will have to write a seperate maxf function for 2D array as the one with 1D array won't work.

Steps:

Set the 1st elements A(1,1) as the max value.
use 2 for loops; one nested into another and run through the whole matrix one by one and check whether the value of the element is greater than the current max value.

Personally I'll reccomend the 1st Method.

Try it..

A. Write a function in MATLAB called findTranspose that takes in as input any matrix or any vector and simply returns back the transpose of that input. You can always verify your answer by using the inbuilt transpose function in MATLAB, however, you cannot use the transpose function directly when writing your code. Here is the starter code that we are providing to help you get started %x is the input vector or matrix. You can find the %size that...

Write a C++ function that takes a two dimensional dynamic array (matrix) and its sizes and returns true if the matrix is an upper matrix and returns false otherwise. Remark: A matrix M is an upper matrix if it is a square matrix (row size = column size) and every element M[i][j] = 0 for all i > j. That is all the elements of the matrix below the main diagonal are zero.

B. Write a function in MATLAB called findInverseOf2x2Matrix that takes in as input any square matrix of size 2 × 2 and returns back the inverse of that matrix if one exists. If no inverse exists, print back a suitable error message. You can safely assume that we will test your code on square matrices of size 2 × 2 only. You can always verify your answer by using the inbuilt inverse function in MATLAB, however, you cannot use the...

MATLAB Function: (Backward substitution) Write a function that takes an upper triangular matrix U, and a vector b as input and returns the solution of the linear system U x = b. Use this function in the case when U is made of the numbers [(3,2,1),(0,5,4),(0,0,6)], and b = [1,1,−6]^T.

Write a Matlab function called “SimpleChannel” which takes a signal as an input, simulates a channel and returns the transmitted signal.. SimpleChannel function will add a randomly generated noise (look for “rand” function) to the signal and return it. You can adjust the amplitude of the noise as you want in order to have a distinct noise effect. Then write another matlab code to show the channel noise. First create the signal and then simulate the channel by using your...

C++ write a function called divideBy that takes two integers as its input and returns the remainder. If the divisor is 0, the function should return -1, else it should return the remainder to the calling function.

Write a function to solve the two-dimensional in Matlab, unsteady heat conduction equation with no internal heat generation on a square domain. The length of each side of the square is 1 m. The function will have the following 4 inputs: npts number of grid points in each coordinate direction nt number of time steps to take dt size of time step (s) alpha thermal diffusivity (m2/s) Use the following initial and boundary conditions: Initialize the body to T =...

JavaScript Write a function called "first" that takes in two arguments - the first is an argument called arr that is an array of numbers, the second is an optional number argument called num(hint: you'll need a default value - look back at the slides). If "num" was not passed in (since it's optional), the "first" function will return an array containing the first item of the array. If a value for "num" was given, the "first" function will return...

Using Matlab, write a function that takes numeric data as its input argument and prints a message to the Command Window stating if the number is positive, or negative, or 0. This function should transfer an output value to the Workspace ONLY when the input value is negative. Please include a copiable code and the associated screenshots.
