prepvalidation

Preparation of the validation parameter vectors

Syntax

varparam = prepvalidation(param)
varparam = prepvalidation(param,'Property',Value)

Parameters

• param - Validation parameter settings (struct array)

Returns

• varparam - Cell array of parameter combinations

Description

varparam = prepvalidation(param)

Returns all the possible permutations of the parameters in the input structure array param. All possible combinations are randomly permuted and returned as a cell array. The param structure must have to following fields for all of the N parameters:

• param(n).name - Name of the parameter in the script (string)
• param(n).values - Values to be adapted by the parameter (Cell or numerical array)

Important

This function is automatically called by sensitivan, where the param structure and not varparam must be passed.

For example, a case where two parameters varA and varB are to be validated. The first parameter should be validated times at for the strings 'str1' and 'str2' and the second parameter should be linearly validated 3 times in the range 5 to 15:

%Validation parameter varA
param(1).name = 'varA';
param(2).values = {'str1','str2'};

%Validation parameter varB
param(2).name = 'varB';
param(2).values = linspace(5,15,3);

varparam = prepvalidation(param);

which will compute all the possible combinations of the values of the first and the second parameter. The cell array varparam will contain the following permutations:

Combination #	varA	varB
1	'str1'	5
2	'str2'	5
3	'str1'	10
4	'str2'	10
5	'str1'	15
6	'str2'	15

Additional Settings

Additional settings can be specified via name-value pairs. All property names are case insensitive and the property-value pairs can be passed in any order after the required input arguments have been passed.

varparam = prepvalidation(param,'Property1',Value1,'Property2',Value2)

RandPerm

Specifies whether to randomly permute the validation parameters combinations.

Default: true

Example:

varparam = prepvalidation(param,'RandPerm',false)
