An array of variable names that match the criteria given by the keywords. If no matches are found a scalar NULL string is returned.
Standard Library function that scans for PV-WAVE variables that match the given criteria.
An array of variable names that match the criteria given by the keywords. If no matches are found a scalar NULL string is returned.
If set, returns the number of variables that matched the criteria.Dimensions
A string or string array specifying the exact dimensions of the variable(s) that you wish to have returned. If an array, returns variables matching any o*f the dimensions. The string must have the following pattern:
'NxNx...xN' or
['NxNx...xN', ..., 'NxNx...xN']For example:
Dimensions = '256x256x3', or
Dimensions = ['256x256x3', '3x512', '3x640'] If you set Dimensions equal to
N, it will return all 1D arrays with N elements. Similarly, Dimensions = '0' will return all scalar variables (much like specifying NDimensions = 0)Level
Specifies the program level for which variables are to be considered.
0, levels are counted up from $MAIN$ to the current level. If Level
0, levels are counted down from the current level. If this keyword is not specified, $MAIN$ is assumed.
Specifies patterns to be matched. The patterns are used to find and display variable names. If this keyword is not specified, all variables are considered. As with INFO, the asterisk (*) and question mark (?) may be used to match any string or a single character, respectively. NDimensions
A scalar or array specifying the number of dimensions to be matched.Type
A scalar or array specifying the type(s) of variables to be matched, according to the following table:
var_list = VAR_MATCH(Dimensions = '3x256', Type = [1, 2, 3])
