Function Documentation

copy()

function copy	(	in	from,
		in	to,
		in	fields
	)

Copy the contents of the struct/object from to the struct/object to recursively and without destroying the existing components in to.

Parameters

[in]	from	: The input scalar MATLAB struct whose (select) components must be copy/merged with the components of the input struct to.
[in]	to	: The input scalar MATLAB struct to which the components of from struct must be copied. (optional, default = struct())
[in]	fields	: The input vector of MATLAB strings each element of which is a field name in from whose value has to be copied to the struct to. (optional, default = fieldnames(from) or properties(from))

Returns

tonew : The output MATLAB struct containing the merger of the two input MATLAB structs.
If a field name in fields is common between from and to, the field value of from will overwrite the corresponding field value of to in the output tonew.

Possible calling interfaces ⛓

tonew = pm.matlab.struct.copy(from)
tonew = pm.matlab.struct.copy(from, to)
tonew = pm.matlab.struct.copy(from, [], fields)
tonew = pm.matlab.struct.copy(from, to, fields)

Example usage ⛓

cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.
addpath('../../../../'); % Add the ParaMonte library root directory to the search path.
 
pm.matlab.show()
pm.matlab.show('from = struct("key1", 1, "key2", "val2", "Key2", "val2duplicate", "key3", false, "key4", []);')
                from = struct("key1", 1, "key2", "val2", "Key2", "val2duplicate", "key3", false, "key4", []);
pm.matlab.show('to = struct("key1", "val1", "Key2", "Val2");')
                to = struct("key1", "val1", "Key2", "Val2");
 
pm.matlab.show()
pm.matlab.show('new = pm.matlab.struct.copy(from);')
                new = pm.matlab.struct.copy(from);
pm.matlab.show('new')
pm.matlab.show( new )
 
pm.matlab.show()
pm.matlab.show('new = pm.matlab.struct.copy(from, [], "key3");')
                new = pm.matlab.struct.copy(from, [], "key3");
pm.matlab.show('new')
pm.matlab.show( new )
 
pm.matlab.show()
pm.matlab.show('new = pm.matlab.struct.copy(from, to, "key3");')
