Use MATLAB code to code a program to find roots for (a)-(b). Set stop criterion|xL - XRl < E = 0.001. Provide all the results and code for (b). Apply

Secant method with interval end-points as starting points to determine roots of the following equations to three significant decimal figures. \text { a. } 3 x^{3}-2 x^{2}-3 x+12=0 \text { b. } 3 x^{5}-2 x^{4}+4 x^{3}+5 x^{2}-16=0 \text {, }
