( MATLAB) How to answer this

The monthly payment M of a mortgage P for n years with a fixed annual interest rate r can be calculated by the formula:

M=Pr12+(1+r12)12n(1+r12)12n1M=Pr12+(1+r12)12n(1+r12)12n1 ( See the Pic for the equation)

Determine the monthly payment of a 30-year $450,000 mortgage with interest rate of 4.2% (r = 0.042). Define the variables P, r, and n and then use them in the formula to calculate M.
