Passing name-value arguments to a function that calls feval

Hello,

Is it possible to pass name-value arguments to a function that calls feval? If yes, what is the syntax? The problem looks like this:

% I want to pass any number of name-value pairs here
r = frun(@fA,argA1=2)

% ========================================================================
function r = frun(fh,varargin)
% Function that calls feval
r = feval(fh,varargin);
end

% ========================================================================
function resA = fA(namedArgs)
% Test function A
arguments
    namedArgs.argA1 (1,1) double = 1
    namedArgs.argA2 (1,1) double = 1
    namedArgs.argA3 (1,1) double = 1
end
resA = namedArgs.argA1 + namedArgs.argA2 + namedArgs.argA3;
end

Thanks

Use varargin{:} to send the contents of varargin to the feval function as a comma-separated list of arguments.

% I want to pass any number of name-value pairs here
r = frun(@fA,argA1=2)

r = 4

% ========================================================================
function r = frun(fh,varargin)
% Function that calls feval
r = feval(fh,varargin{:});
end

% ========================================================================
function resA = fA(namedArgs)
% Test function A
arguments
    namedArgs.argA1 (1,1) double = 1
    namedArgs.argA2 (1,1) double = 1
    namedArgs.argA3 (1,1) double = 1
end
resA = namedArgs.argA1 + namedArgs.argA2 + namedArgs.argA3;
end
