Function Synopsis
paraopt = paraoptset(PARAOPTDEF, varargin)
Help text
Create/alter PARAOPTions structure
This function creates or alters options structures.
This function can be used for:
- creating a new complete options structure, all values set to defaults
- create a new partial options structure with given properties
- combine two or more options structures into one
- change given properties of a options structure
The Example section below provides examples for all these possibilities.
Syntax: paraopt = paraoptset(PARAOPTDEF, P1, P2, P3, P4, ...)
Input parameter:
PARAOPTDEF - Cell array defining the nameof possible options, their type,
default value and a possible dimensionality
P1 ... - Parameters/options and their values in name/value pairs
See Examples below for description of possible inputs types and their
corresponding functionality.
Output parameter:
PARAOPT - Structure with newly defined options
See also: paraoptload, paraoptsave, paraoptpropprint (private), fieldnames_parts, fieldnames_full
Examples:
paraoptset
Called with no input and output arguments displays all property names and
their possible values, including the default value. paraoptset property
defaults for any unspecified property are taken from the values specified
inside this function.
paraopt_full = paraoptset
Called with no input arguments returns a paraoptions structure with all
possible property names and set to their default value.
paraopt_part = paraoptset('name', value1, 'name2', value2, ...)
Creates a partial paraoptions structure in which the given
properties have the specified values. It is sufficient to
type only the leading characters that uniquely identify the property.
Case is ignored for the property names.
paraopt_part = paraoptset('Mutation.Name', 'mutint', 'Mutation.Range', 0.1)
The structure paraopt_part contains just the fields 'Mutation.Name'
and 'Mutation.Range' set to the specified values.
paraopt = paraoptset(paraopt_part, 'name1', value1, ...)
Alters an existing paraoptions structure paraopt_part using the given
properties.
paraopt_new = paraoptset(paraopt_part, 'Recombination.Name', 'recdis', Mutation.Name', 'mutreal')
The structure paraopt_part defined in the previous example is extended
with the property 'Recombination.Name'. The property 'Mutation.Name'
is set to a new value.
paraopt = paraoptset(paraoptold, paraoptnew)
Combines an existing paraoptions structure paraoptold with a new
paraoptions structure paraoptnew. Any new properties overwrite
corresponding old properties.
paraopt_all = paraoptset(paraoptset, paraopt_new)
The full and default structure returned by paraoptset (see second
example above) is redefined with the properties from paraopt_new,
which was preset in the examples above.
paraopt = paraoptset(paraoptcheck)
When called with just one paraoptions structure as input parameter, the values
of these properties are checked (violation of boundaries, when multi strategy - then
the number of values is set to the number of subpopulations and so on).
