Working on different projects I have written simple Matlab demos which helped me to understand certain mathematical concepts or models by enabling me to easily manipulate their parameters and observe the resulting changes. Here I provide the Matlab code of the demos and some explanations in the hope that they are helpful to a wider audience. Click on the screenshots to download the corresponding demo!
1D Gabor Filter
In neuroscience Gabor filters have been proposed as a model for the receptive fields of neurons in early visual cortex. These filters are defined in two dimensions, but many properties of the Gabor filter can already be understood in one dimension. So here is a Matlab GUI which demonstrates how the 1D Gabor filter can be manipulated. The underlying function is:
