javascript only: You have been assigned to work with an undersea explorer who is attempting to identify and map undersea trenches. The explorer has provided you with several data sets. Depending on the scan, the provided matrix may be larger or smaller, but it will always be rectangular. Your task is to determine if a given data set contains a trench by comparing each node and their neighbors and determining if there is a pattern that matches the defined properties of a trench. Neighbors are considered to be nodes that are directly above, below, or to the side. No diagonals! A trench has the following three properties: It has a length of three or more nodes that are neighbors. Each node in the trench must be deeper than -5. Trenches may not branch into (any form of) a "T" shape. A node with more than two neighbors will result in branching "T" shape. // Example 1 sonar = [ [-5,-5,-5,-5,-5], [-5,-8,-8,-9,-7], [-5,-5,-5,-5,-8], [-5,-5,-5,-5,-5] ]

for a 1000x5 matrix where each column is a specific data for profit  r=randi(10,1000,5) write a matlab code that asks the user from which of 5 column to select and to display the count to the user the number of days each value in the selected column was higher than the overall mean of the matrix.please use matlab!

Given the Verilog skeleton code given in the example document for this quiz. Replace and with the code below and determine y_tb and z_tb at the time stated. Note that the ^ symbol means XOR. y = a ^ -b; z = a | c; a_tb = 1; b_tb = 1; c_tb= 0; #10 a_tb = 0; #20 b_tb = 0; Find y_tb and z_tb at time 50. O a. y_tb = 0, z_tb = 0 O b.y_tb = 0, z_tb = 1 O C. y_tb = 1, z_tb = 0 d. y_tb = 1, z_tb = 1
