CL_defParam

Definition of parameter structure for CL_inputParam

Calling Sequence

[par] = CL_defParam(text, val, id, units, dim, typ, accv, valid)

Description

Parameters

text:

Text defining the parameter. Empty string by default.

val:

Initial value (given in internal unit). 0 or ' ' (empty string) by default.

id:

Identifier (string) useable in the 'valid' expression. Empty string by default.

units:

[unit1, [unit2]] (strings), where unit1 is the internal unit (unit of val), and unit2 the unit used for input (unit2is the same as unit1 by default). By default: no units. If unit2 is defined, CL_unitConvert is used to convert from unit1 to unit2.

dim:

Number of expected values. Default is 1. A value of -1 means 'any number including 0' (vector).

typ:

Type of parameter: 'r' (real) only is handled (default).

accv:

Vector (1xN) of accepted values. By default: [], meaning that everything is accepted. NB: if units are defined, values in accv must be expressed in 'input' units (i.e. unit2).

valid:

Expression (string) used to check the validity of the value. The expression used should be compatible with 'find' if many values are expected (i.e. if dim <> 1). NB: if units are defined, the values are checked while expressed in 'input' unit(i.e unit2), not internal unit.

par:

Parameter structure.
