how to get the highest power of polynomial matlab

To obtain the highest power of a polynomial in Matlab, you can use the length function to determine the number of coefficients in the polynomial and subtract 1. Here is the code snippet:

coefficients = [1, 2, 3, 4]; % example coefficients of a polynomial
highest_power = length(coefficients) - 1;

In this example, the coefficients variable represents the coefficients of the polynomial. You can replace it with the coefficients of your specific polynomial. The highest_power variable will store the highest power of the polynomial.

Note that the length function returns the number of elements in an array. Since the coefficients of a polynomial are typically stored in descending order of powers, the highest power of the polynomial is equal to the number of coefficients minus 1.

I hope this helps! Let me know if you have any further questions.
