Matrix Exp (G Dataflow)

Last Modified: January 9, 2017

Computes the exponential of a square matrix by using the Pade Approximation method.



A square matrix.

This input accepts a 2D array of double-precision, floating point numbers or 2D array of complex double-precision, floating point numbers.


error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error


matrix exp

The exponential of the input matrix.


error out

Error information. The node produces this output according to standard error behavior.

Algorithm for Calculating the Exponential of a Matrix

The following equation defines the exponential of a matrix:

e A = n = 0 A N n ! = I + A + A * A 2 ! + A * A * A 3 ! +

where I is the identity matrix.

This node uses the Pade Approximation method to calculate the exponential.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported
