Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.

Exponential Integrators: Numerical methods that use the matrix exponential to integrate the linear part of a differential equation exactly, thereby mitigating stiffness-related challenges.

The exponential function is all about growth, and growth follows a logical curve. It can be linear or exponential. Linear is what children do as they grow in weight.
