Slide3 l.jpg

Starting MATLAB

  • Desktop Demo

  • type demo matlab desktop in the prompt ,and then start a „desktop environment“ demo


Slide4 l.jpg

First steps. Learning by doing

  • Matrix Manipulations


Slide5 l.jpg

Data analysis

  • Importing Data

  • type demo matlab desktop in the prompt ,and then start a „importing data“

  • Data Analysis Demo

  • Interpolation Demo


Slide6 l.jpg

3-D plots

  • Mexican hat function


Slide7 l.jpg

Poisson spike train generator

  • Exercise 3

Spike times: ti

Interspike interval distribution: P[τ ≤ ti+1 - ti < τ +Δt] = rΔt exp(rτ).

Formula for generation: ti+1 = ti - ln(xrand)/r.

Relative refractory period:

Autocorrelation function

T

  • Weak coupling with homogeneous input

  • Weak coupling with noisy tuned input

  • Strong coupling with noisy tuned input

  • Strong coupling with nonspecific input
