Write a function script DirCos.m that takes a vector (any row or column array) as the argument and returns the direction cosines for that vector. This is for a MatLab script

Solutions

Expert Solution

Consider a vector a.i + b.j + c.k, Where a,b,c are the direction magnitudes and i,j,k are unit functions.

This vector can be represented as <a   b   c>

Direction cosine of the vector are,

cos =

cos =

cos =

MATLAB CODE

for i=1:3
a(i) = input("Enter the value of vector : ");
v(i) = a(i)/sqrt(sum(a.^2));
end
fprintf("\n Given vector is \n");
disp(a)
fprintf("Direction cosine of the given vector is \n");
disp(v)

OUTPUT EXAMPLE

>> DirCos

Enter the value of vector : 1
Enter the value of vector : -2
Enter the value of vector : -3

Given vector is
   1 -2 -3
Direction cosine of the given vector is
   0.26726 -0.53452 -0.80178

Write a function called ReturnOddEntries.m that accepts as input a column or row array (vector) and returns only the odd index entries. Do this by first setting the even entries to 0, and then removing the 0 entries by using a logical array. The first line of your code should read function p = ReturnOddEntries(p) For example, if you run in the command window p = ReturnOddEntries([1.2 7.1 8.4 -42 100.1 7 -2 4 6]), then you should get p...

Write a function that will accept one integer matrix E and one column vector F by reference parameters, and one integer I as a value parameter. The function will return an integer v, which is the i-th coefficient of row vector denoted by E*F (multiplication of E and F). For example, if V = E*F, the function will return v, which is equal to V[i]. Explain the time complexity of this function inside of the function code as a comment....
