Introduction The aim of these demos is to provide an introduction to how to program using Psychtoolbox PTB. To get started you will need to have installed Matlab or Octave a free version of Matlab and followed the install instructions which are provided here on the PTB website please read the instructions before installing, most errors are due to simply not reading the installation instructions. There are around 40 demos on this site and these are organised into sections based on learning different aspects of PTB. For all users I strongly suggest looking at sections 1 and 2 as these show essential features which will help get you up to speed coding in Matlab and PTB.

### Vector mirror?

What is not completely obvious is how to go from the vector F that you get to an amplitude or phase spectrum that is correctly scaled and has the right frequencies associated with the values in F. This is particularly tricky because there are some subtle differences between the results when the time series has an even or odd number of samples. Nfft will typically be the number of points in the time series or lenght ts -this is the default behavior, but it can be overridden. The vector F then contains the complex-valued amplitudes for all of the discrete frequencies going from -Nyq to Nyq where Nyq is the Nyquist frequency or almost. Because we are usuall looking at real signals, the absolute value of the amplitudes for the positive frequencies are the same as that of the corresponding negative frequency, so the vector F is almost symmetric. Here is how the values are arranged:
