Is the matrix exponential an ordinary exponential function?
Matrix exponential. In mathematics, the matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function.
Is the rate of change proportional to the exponential function?
More generally, a function with a rate of change proportional to the function itself (rather than equal to it) is expressible in terms of the exponential function. This function property leads to exponential growth or exponential decay . The exponential function extends to an entire function on the complex plane.
How is the magnitude of the exponential function increasing?
The transition from dark to light colors shows that the magnitude of the exponential function is increasing to the right. The periodic horizontal bands indicate that the exponential function is periodic in the imaginary part of its argument.
Which is the most common definition of an exponential function?
The most common definition of the complex exponential function parallels the power series definition for real arguments, where the real variable is replaced by a complex one: Alternatively, the complex exponential function may defined by modelling the limit definition for real arguments, but with the real variable replaced by a complex one:
What is the data type of an exponential?
Exponential values, returned as a scalar, vector, matrix, or multidimensional array. For real values of X in the interval (-Inf, Inf), Y is in the interval (0,Inf). For complex values of X, Y is complex. The data type of Y is the same as that of X.
How are exponential values returned in MATLAB exp?
Exponential values, returned as a scalar, vector, matrix, or multidimensional array. For real values of X in the interval (- Inf, Inf ), Y is in the interval ( 0, Inf ). For complex values of X, Y is complex. The data type of Y is the same as that of X.
How is the matrix exponential used in the theory of Lie groups?
It is used to solve systems of linear differential equations. In the theory of Lie groups, the matrix exponential gives the connection between a matrix Lie algebra and the corresponding Lie group . Let X be an n×n real or complex matrix.
