Do you mean that we need to give input for few parameters and they should be used for the next steps?

function varargout = YourFunction(varargin)
argnames = {'x', 'y', 'n'};
for K = 1 : length(argnames)
if nargin < K || isempty(varargin{K}) || any(isnan(varargin{K}(:)))
new_parameter = input( sprintf('Enter a value for %s ', argnames{K} ) );
newargs = varargin;
newargs{K} = new_parameter;
[varargout{:}] = YourFunction(newargs{L});
return
end
end
%if you got here, your argument validation passed, so do your regular computation
end
