hello, i've got an embedded matlab function with several parameters(variables). I try to enable/disable parameter 1 and 2 in dependency on parameter 3. Means, if the value of parameter 3 is "1", parameter 1 is enabled and parameter 2 is disabled. If the value of parameter 3 is "2", both parameters are enabled. Is there a possibility for this?

yes, for example i have the parameters a,b,c,d and a function y=a+b+c. If parameter "d" has the value 1 --> y=a. if parameter "d" has the valua 2 --> y=a+b. if parameter "d" has the value 3 --> y=a+b+c.
hope this is understandable. Another idee was to enable/disable the inputports for a,b and c

function y=fcn(a,b,c,d)
if d==1
y=a
elseif d==2
y=a+b
elseif d==3
y=a+b+c
end
%or
function y=fcn(a,b,c,d)
v=[a b c];
y=sum(v(1:d))
