API

The public Application Programming Interface (API) of DataLab offers a set of functions to access the DataLab features. Those functions are available in various submodules of the cdl package. The following table lists the available submodules and their purpose:

Submodule	Purpose
cdl.algorithms	Algorithms for data analysis, which operates on NumPy arrays
cdl.param	Convenience module to access the DataLab sets of parameters (instances of guidata.dataset.DataSet objects)
cdl.obj	Convenience module to access the DataLab objects (cdl.obj.SignalObj or cdl.obj.ImageObj) and related functions
cdl.computation	Computation functions, which operate on DataLab objects (cdl.obj.SignalObj or cdl.obj.ImageObj)
cdl.proxy	Proxy objects to access the DataLab interface from a Python script or a remote application
