Write a user-defined function that determines the value that occurs most often in a set of data that is given in a two-dimensional matrix. For the func- tion name and arguments, use [v, q] =matrixmode (x). The input argu- ment x is a m×n matrix of any size with numerical values, and the output arguments v and q are the values that occur most often and the number of times they occur. If there are two, or more, values that occur most often than v is a vector with these values. Do not use the MATLAB built-in func- tion mode. Test the function three times. For input create a 5×6 matrix using the following command: x=randi (10,5,6).

In the following questions you need to import functions from Numpy. For example the computation of matrix determinants can be done with the help of the function det of the library numpy.linalg. Please list the commands required for the function to work

1. Write a functionSummOddthat will find the sum of all elements of odd ordera1+a3+...of a given a array. Pass an array arr[ ] and a dimension n and return the value of the suma1+a3+...asthe function’s return value. Call this function in themain()with arr[ ]={8,6,4,2,3,5}and dimensionn=6 to test the correctness of your general function. Keywords: Write function, pass array and dimension, return sum of odd order

Write a function named mean that accepts as a parameter a reference to a vector of real numbers, and returns the arithmetic mean (average) of the integers in the vector as a real number. For example, if the vector passed contains {2.0, 4.5, 6.5, 1.0}, your function should return 3.5. If the vector is empty, return 0.0. Do not modify the vector that is passed in.
