MATLAB QUESTIONS

1. [1pts] Create the following vectors (prob01a, b):

   1. A = 10 thru 1

   2. B = 1 thru 4.2 with ten equally spaced elements

2. [3pts] Perform the following operations on the vectors A and B element by element (prob02a, b, c)

   1. multiply B and A

   2. divide B by A

   3. AB + BA

3. [3pts] Create a matrix E, using A and B vectors as row 1 and row 2 respectively (prob03a, b, c)

   1. find the size of E

   2. find the length of E

   3. find the single value minimum of E

4. [4pts] Find the indices (row and col) within E where (prob04a, b, c, d)

   1. E = 5

   2. E > 4

   3. E < 1.9

   4. E > 1 and E < 2

Answer 1

For the above prolem, we need to have the following things into consideration.

1. We need to create the vectors of the specifies length and increments
2. Then we need to do the operations as specified in the problem.

Following is the code for the same.

% Defining the A from 10 to 1 
a = 10:-1:1;
% Making B from 1 to 4.2 with the increment such that it makes 10 elements
b = 1:3.2/9:4.2;
% Doing the operations element by element
disp(b.*a)
disp(b./a)
disp(a.*b + b.*a)

Following is the snippet of the code.

Following is the output snippet.
