Need help with Matlab code

Write a Matlab program that prompts the user for a number called DDC whose values should be between 0 and 999, inclusive. Check that the user has entered a value in that range and print an error if he didn't. Using cascaded if statements (meaning the first time the condition is true, the rest of the conditions in the cascade are not evaluated), convert that number into a string, according to the following system and store the string in a string (chart array) variable General works Computer science and Information 000 DDC Philosophy and psychology Religion Social Sciences Language 099 100 DDC 199 200 DDC 299 300 DDC 399 400 DDC 499 500 DDC 599 Subject Pure Science Technology Arts&Recreation; Literature History aGeography 700 DDC 799 900 DDC999 Print the value of the stored character variable as the Dewey Decimal Class

Explanation / Answer

syms x df = diff(tan(x*pi/180),x) df = (pi*(tan((pi*x)/180)^2 + 1))/180 vpa(subs(df,x,1)) ans = 0.01745861017674520251875419598381
