Class: DataMatrix
A matrix object loaded from a data source.
Inherits: Matrix
DataMatrix ( source, field [, xStart, yStart, xN, yN [, skip [, ave]]] )
reload ( )
changeFile ( source )
change ( xStart, yStart, xCount, yCount [, skip [, ave]] )
DataSource source - The DataSource to load data from. This may be a string containing the url of the DataSource to load. If so, it will attempt to reuse an existing DataSource instance, or fall back to a new DataSource object. It may also be specified as a DataSource object.
string field - The field to load from the source.
number xStart - The x frame to start reading from. [OPTIONAL]
number yStart - The y frame to start reading from.
number xN - The number of x frames to read.
number yN - The number of y frames to read.
number skip - The number of samples to skip by. [OPTIONAL]
boolean ave - Set to true to do boxcar filtering. [OPTIONAL]
DataSource source - The DataSource to switch to.
number xStart - The x starting frame.
number yStart - The y starting frame.
number xCount - The number of x frames to read.
number yCount - The number of y frames to read.
number skip - The number of frames to skip by. [OPTIONAL]
boolean ave - True to boxcar filter. [OPTIONAL]
True if the matrix should skip by skipLength samples while reading from the data source.
If true, the matrix is read to the end of the source in the x dimension.
If true, the matrix is read to the end of the source in the y dimension.
If true, the matrix reads only a maximum number of samples from the end of the source in the x dimension.
If true, the matrix reads only a maximum number of samples from the end of the source in the y dimension.
The data source object used by this DataMatrix.
