Could anyone help me to check this script? I created a matrix "a" with the size of 150 by 200, in the for loop, I want to update the sum of all entries of the matrix after each stepsize of k and store it to the b vector. However, I feel like I might have done something wrong because when I check the vector b in the worksapce, b(1); b(2).... is so small. Thank you.
we can update this script in maths work lab

Suppose the hurricane in Figure 2 has stalled off the southeast coast of the United States. Further suppose that the peak winds around the storm are 115 mi/hr and that its central pressure is 934 millibars (27.58 inches). If the hurricane begins to move due west at 10 mi/hr, answer the following questions assuming that the hurricane experiences no change in its intensity. a. On which side of the hurricane (north, south, east or west) would you expect the winds...
I am creating a MATLAB game for my school project. The goal of the game is to create a 'Treasure Hunt Game' that asks the user to input the number of players, the difficult (easy, medium, or hard), and asks the user(s) to pick spots on a matrix until the correct spot is chosen, therefore winning the game. If a player misses the spot, the command window doesn't show how far away the treasure is, but what direction it is...
In this graded tutorial you will learn how to use Excel’s INDEX and MATCH functions. If you are familiar with the VLOOKUP function, INDEX/MATCH is often seen as a better method to accomplish the same goal. The Excel INDEX function returns a value in a range based on the row and/or column numbers that are specified. Its format is INDEX(array, row_num, [column_num]). Note that column_num is optional. For example, assume you have the simple data below: A B 1 North...

In this exercise, you will work with a QR factorization of an mxn matrix. We will proceed in the way that is chosen by MATLAB, which is different from the textbook presentation. An mxn matrix A can be presented as a product of a unitary (or orthogonal) mxm matrix Q and an upper-triangular m × n matrix R, that is, A = Q * R . Theory: a square mxm matrix Q is called unitary (or orthogona) if -,or equivalently,...
