IN MATLAB

For the problems below, do not use semicolon to suppress the outputs. 1. Define a vector called a, starting at -1, incrementing at 2, and ending at 20. 2. Define a vector called b, starting at -1, decrementing at -1, and ending at -10 3. Define a vector called c, which contains 100 points, starting at -1 and ending at 20. Use the linspace command to help you create the vector. For example, linspace(-pi, pi, 1000) will create a vector of 1,000 elements whose starting point is and ending point a. 4. Let vector_length be the length of the vector c from Problem 3. Check that the vector c does have 100 elements by using the MATLAB function length. 5. Create a vector called v, starting at 0, incrementing at 1, and ending at 5. 6. Evalute cos(1x) at v and call the result eval. (This avoids evaluating cos (1x) at different multiple of a using for loop.)
