Evriscript

Purpose

EVRISCRIPT objects allow calling various PLS_Toolbox operations in an object-oriented way. A script can contain one or more steps, each of which is a separate object with its own inputs and outputs. Each step is defined by a keyword which represents the type of step (known as a module) to perform.

Synopsis

myscript = evriscript(keyword,keyword,...);  % create a script with two or more steps

Description

Creating a script

Call evriscript with parameters indicating the sequence of steps to perform, each step indicated by its keyword. The list of available step keywords is given by the command: evriscript_module('showall') Example, myscript = evriscript( 'pls', 'crossval', 'choosecomp', 'pls');

  evriscript(keyword,keyword,...)

'myscript' is an evriscript object. The script steps are evriscript_step objects which can be accessed by indexing, 'myscript(1)', for example.

The individual steps' properties are then configured. Most steps have more than one 'step_mode', for example 'calibrate', 'apply' or 'test'. You can see which step_modes are avaialable for a step by entering myscript(1).step_module. This also shows the required and optional properties associated with the step for each step_mode. The 'calibrate' step_mode lists required properties as: 'x', 'y', and 'ncomp'.
