Hello. Can you help me in finding the appropriate solution by using MATLAB commands

Homework 1-If x= [ 2 6 12: 15 6 3; 10 11 11. then a) replace the first row elements of matrix x with its average value, b) reshape this matrix into row vector. 2-If x= [2 & 5; 9 7 1], b= [2 4 5] find: a) find the maximum and minimum of x. b) find median value over each row of x. c) add the vector b as a third row to x. 3- Compute the standard deviation by using the following equations then compare the result with that one obtained by std command. -5) n-1 11 14 11 ] n
