THIS IS FOR Matlab program, not other programs

Create the function described below: Function name should be problem_2 Function should accept 1 input arguments. The input argument (parameter) should be called fibn and represents which term of the fibonacci sequence you want to calculate. Function should have 1 output argument. The output argument (return argument) should be called result. The function body should do the following: Calculate the nth term of the fibonacci sequence (using the parameter fibn) using binet's formula and return the answer in the variable called result. It's ok if it only works for small values of the fibonnaci sequence (where fibn is
