Function Documentation

repKeyVal()

function repKeyVal	(	in	key,
		in	val,
		in	hashmap
	)

Return the input hashmap with the new (key, val) appended, only if the input pair does not exist in the input hashmap.
If the pair exists, replace it with the new value.

Parameters

[in]	key	: The input scalar MATLAB string containing the key to add to the input pair list.
[in]	val	: The input value to be appended to the input hashmap after the input key.
[in]	hashmap	: The input cell array of even number of elements containing the (key, val) pairs of the hashmap in sequence as element of the cell array.

Returns

hashnew : The output cell array of even number of elements containing the input pair list and (key, val) pair.
If the input key exists in the input hashmap, the input (key, val) pair will not be added.

Possible calling interfaces ⛓

hashnew = pm.matlab.hashmap.repKeyVal(key, val, hashmap)

Example usage ⛓

cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.
addpath('../../../../'); % Add the ParaMonte library root directory to the search path.
