Exponential
This block implements the power function given the base as block parameter: y=a^u where a is the block parameter and u is the input. If a equals exp(1), then the operation corresponds to the exponential function.

Description
The Exponential block implements the power function given the base as block parameter: y=a^u where a is the block parameter and u is the input. If a equals exp(1), then the operation corresponds to the exponential function.
The input u is either a scalar, a vector or a matrix.
The block performs element-wise exponential when input is a matrix. To compute a matrix exponential, use the MatrixExponential block instead.
