Octave assignment

Objectives Download Octave and run it or use https://octave-online.net/ Learn the basics of the Octave GUI. Learn how to create a short executable file called an m-file (.m extension) and run it. Learn how to declare variables. Learn how to create matrices. Learn how to use several of Octave's functions for creating objects with random numbers. Learn how to graph a function. Learn how to annotate a graph. AVI wuS assignment. Instructions 1.) Create an m-file called my_quad_last name_first name. 2.) All of your code will go between two keywords: function and endfunction. The first line will include function. 3.) Since we'll be integrating, we'll need limits of integration. The limits of integration, a and b, will be inputs to your function. 4.) Create 6 matrices of evenly spaced values of x over [a, b]. The spacings should be 0.05, 0.01, 0.05, 0.1, 0.25, and 0.5. Call them x1, x2, x3, x4, x5, and x6. The first one would look something like x1 = (a:0.01:b) (you can also use linspace if you want). 5.) Evaluate the function y = cx2 + d over each interval, where c and d are inputs to your function. Call them y1, y2, y3, y4, y5, and y6. 6.) For yl, y2, y3, y4, y5, and y6 call the trapz function. For the first set, the syntax is Al = trapz(x1, y1). This function returns a value, which is the area under the curve, and you store it in the variable A1. Do this for each pair of x and y. Store the areas in the variables Al, A2, A3, A4, A5, and A6. 7.) Make a new matrix delx = [0.05, 0.01, 0.05, 0.1, 0.25, 0.5] and A = [A1, A2, A3, A4, A5, A6]. 8.) Plot delx versus A. Label the axes and give it a title. 9.) Calculate the exact area under the curve (do an integral by hand). Print the exact value using the disp function. 10.) Using the disp function, describe the values returned by the trapz function in relation to the exact value. C..L
