Code examples in Matlab for the simulation and visualization of behavioral data.
Other examples of visualization of live behavior can be found in:
- Model-based and Model-free RL solving a sequential two-choice Markov decision task
- ON and OFF policy solutions for the “windy grid-world task”
- ON and OFF policy solutions for the cliff task
Of course it is not necessary to visualize the behavior of the artificial agents to mathematically describe the computations required to solve a task, but it is helpful to see the behavior to understand how this is shaped by rewards and punishments in the environment.

Virtual fly test tube
In an ongoing collaboration with dr Frank Hirth’s lab, a couple of months ago I have been invited to generate the code for a simulated insect navigating a virtual 2-dimensional world. This investigation aimed at testing whether a recently developed neural model of the central complex in insects (i.e. see…
Randomly sampled TTest comparison
The following code has been used to compare couples of vectors in a given structure composed of 4×12 cells which result from simulated results of 4×12 model genotypes (download archive here). Most vectors have a similar dimension (175), but some differ, requiring a multiple random comparison by permutation. The final distribution of…
Continuous error band in Matlab
I was looking for a plot function in Matlab that could create error “bands” with a continuous filled plot for the standard error, highlighting the mean. In the end I decided to create the function I needed so that I could have the parameters I wanted: namely colours and transparency. Here…
