In matlab how would this specific code be written and how could I ask the user to enter a vector of coefficients for the polynomial model. Verify that the entry has an even number of elements (an odd number of elements would mean an even order polynomial). If an invalid vector is entered, prompt the user to re-enter the vector until an acceptable vector is entered. If the user does not enter an acceptable vector after 5 attempts (including the first prompt), display a warning and remove the last element of the last vector entered. (For example, if the last user input is [1 2 3 4 5], the vector becomes [1 2 3 4]).

my code

[1,2,3,4];
