# Empirical Convolution Between an Input Function and a Single Exponential

### Description

Computationally efficient method to convolve a vector of observations and a single exponential function with two parameters.

### Usage

1 | ```
expConv(input, k1, k2)
``` |

### Arguments

`input` |
is the so-called input function. |

`k1` |
is the scaling parameter in the single exponential function. |

`k2` |
is the decay parameters in the single exponential function. |

### Details

Assuming the input function has been sampled (or interpolated) to a high temporal resolutions, say one Hertz, a simple for loop is used to perform the convolution.

### Value

The vector containing the result from the convolution operation.
