I need help with these matlab questions

a) Create a MATLAB script that defines a vector whose 10 componets are equal to sin(k4), for k=1,2,,10 b) Create a MATLAB script that defines an 8-componert vector ai values are!) and then outputs a vector: c) Create a MATLAB script that accepts a 5-componet vector [a1a2a3a4a5] where each a1,a2,,a5 is a decimal number, and then outputs the vector where each component is rounded to the nearest whole number. (Use past labs to help you here if necessary!)
