Dear Sir or Madam: I wonder how the function MatrixExp works. Does MatrixExp(A) refer to calculate 
?
For example, A = {{1.2, 3.7, 5.6}, {0, -2.2, 4}, {-5.3, 0, 1.4}}. Firstly, I used the textbook method to compute . The result was shown as below.
Then I computed MatrixExp[A]. The result was shown as below, which is different from the first one.
So what's the problem?
