Use of the exp () function in MATLAB

In MATLAB we often need to use the number of natural logarithm of the base e, the need to enter the different power of E, then we in MATLAB specifically how to operate it. Let's take a look at the different examples below. e Below we have an example of how to enter the natural number, in the MATLAB main window Input exp (1), Enter we can see the natural number logarithm base value e=2.7183 wrong way one : in M Talab The main window, enter E, and enter to see that this is not the natural number logarithm base value. error mode two : Enter exp in MATLAB, enter can see direct input exp, also can not output e value, prompt error when input variable too little. Exp (0) as a special point, we verify the value of exp (0), enter exp (0) in the main MATLAB window, carriage return this is equivalent to E^0=1 exp (a) A is constant we will not say, if a is a vector or matrix, we have to make an example. vector case: with A=[0 1 2] For example, enter A=[0 1 2] in the main MATLAB window , exp (A) Enter can see the power of each vector element respectively. Matrix case : Take a=[0 1; 2 1] For example, enter A=[0 1 in the main window of MATLAB, 2 1] exp (A) Enter can see also the power value of each element of the matrix.
