Writing a code on user input polynomials

Write a code based on user input polynomial that can:

• Ask the user to input the degree of the polynomial.

• Based on the inputted degree, ask the user to input the different polynomial coefficients.

• Generate a range X of values between -100 and 100.

How should this look in matlab?

Hi Lewis,

You can refer to below link for implementation of Polynomials in MATLAB.

https://www.mathworks.com/help/matlab/math/create-and-evaluate-polynomials.html

I am assuming X here is the coefficient values and its range is from -100 to 100.

You can follow the below pseudo code

prompt = 'What is the degree of polynomial ';
degree = input(prompt);

polynomial = [];

for x = 0 to degree
 
prompt = 'What is the original value? ';
y = input(prompt);
if y >=100 & y>= -100
 polynomial(x) =y;
else 
 print(‘invalid value’)
end
