I have a function looks like this. Now, i want add unit in both input and output. For example, if i i run money("dollar", 3), i will get: price= 3 dollar. Or if i run money("dollar",2,3 ), i will get price = 48 dollar. i don't know what code can do this.. please help me, thank you very much.

Is it necessary to pass in the units of the input variable(s)? Does the function body depend upon it for anyting other than providing an output string (or two parameters?) that indicate a numeric value and the unit?

Not exactly sure what formula you're using but this might be close:
price = money('dollar')
price = money('dollar', 2)
price = money('dollar', 2, 3)
function price = money(varargin)
price = '';
% nargin
% varargin
if nargin < 2
return;
end
if nargin >= 2
units = varargin{1};
p = varargin{2};
p0 = varargin{2};
end
if nargin >= 3
exponent = varargin{3};
% Compute p = k * k^2 * k^3 * k^4 * etc.
for k = 2 : exponent
p = p * p0 ^ k;
end
end
price = sprintf('price = %.2f %s', p, units);
end
