Chapter 15, Problem 22ICA
For each of the following problems, write a single MATLAB statement that will accomplish the stated purpose. Assume a text string TS1 has already been defined.
- a. Create a
vector LetLoc with the same number of elements as TS1. For each element of TS1 that is alphabetic, the corresponding element of LetLoc should equal 1. All other elements of LetLoc should be 0. Example: TS1='%@3Gb6* returns LetLoc=[0 o o l l 0] - b. Create a vector Alphas that has the numeric positions of all alphabetic characters in TS1. Example: TS1 ='%@3Gb6' returns Aiphas=[4 5]
- c. Place the numeric index of the first alphabetic character in tsi into Aiphai. Example: TS1 ='%@3Gb6' returns Aiphai=4
- d. Place the last alphabetic character in TS1 into LastLetter. Example: TS1 ='%@3Gb6' LastLetter=b
- e. Find all occurrences of the string @3G in string tsi and place the locations of the first character of each such substring (@) into str3G. Example: TS1='%@3Gb6kl@3G9@33G’ returns Str3G=[2 9]

I need help with a MATLAB code. I need to find two values of n, one that is positive and one that is negative, that will give all negative real roots. Can you help me find them?
function [r] = find_roots(n)
% Define constants I = 400; J = 150; x = (J/I) - 1; y = n - 1; Q = y + x*(y-1);
% Define the coefficients of the quadratic equation coefficients = [1, 0, (3*x+Q^2+1), 0, (3*x*Q+Q^2)];
% Find the roots r = roots(coefficients);
end
