Could you help with the code for this MATLAB problem so I can better understand this concept? Thanks!

4.14. (a) The matriz exponential function of an nxn matrix A is defined by the infinite series AP A3 exp(A) = I + A+ + + ... 2! 3! Write a program to evaluate exp(A) using the foregoing series definition. (6) An alternative way to compute the matrix ex- ponential uses the eigenvalue-eigenvector decom- position A=U diag(41, ..., In) U-1, 4.14.
