The program does interpolation or decimation on a given 1-d data in an array.
Given X with sampling rate Ft Hz and is used to generate another sequence Y with sampling rate Ft' Hz, then Sampling Rate ratio R is given by,
Ft'
R = ----
Ft
if R > 1, sampling process is known as interpolation
R < 1, sampling process is known as decimation
Example Usage:
t = 1:1/10:2;
X = sin...
audioread provides a single, unified function for reading audio files in a range of different file formats, including wav, mp3, aac, flac, AIFF, etc. In most cases, access is actually provided by external binaries, but this is hidden within...
The model simulates a three phase Sinusoidal PWM rectifier. Applied Voltage, switching frequency and sampling factor can be changed from the model properties block.
An affine (or first-order) optic flow model has 6 parameters, describing image translation, dilation, rotation and shear. The class affine_flow provides methods to estimates these parameters for two frames of an image sequence.
