not enough input arguments Error
显示 更早的评论
Dear Colleagues and Teachers,
I am eperiencing a code error aginst this code ;
% Function to generate a multi-step custom membership function
% using 8 parameters for the input argument x
function out = custmf1(x,params)
for i = 1:length(x)
if x(i) < params(1)
y(i) = params(1);
elseif x(i) < params(2)
y(i) = params(2);
elseif x(i) < params(3)
y(i) = params(3);
elseif x(i) < params(4)
y(i) = params(4);
elseif x(i) < params(5)
y(i) = params(5);
elseif x(i) < params(6)
y(i) = params(6);
elseif x(i) < params(7)
y(i) = params(7);
elseif x(i) < params(8)
y(i) = params(8);
else
y(i) = 0;
end
end
out = 0.1*y'; % Scale the output to lie between 0 and 1.
end
Can anyone please tell me that how can i remove this error

Call it as:
out = custmf1(x,params);
with the arguments stated and in the calling script workspace. Only anonymous functions inherit existing workspace variables. Other functions do not.

As always, my pleasure!
Both ‘x’ and ‘params’ must be present in your workspace before you call the function with those arguments.

I am not certain what you want or how it relates to ‘x’ and ‘params’.
One way might be:
f = @(x,NS,NL) ((x>=0.1) & (x<=0.3)).*NL + ((x>0.3) & (x<=0.5)).*NS;
That is how I usually write such conditional statements, avoiding loops and if blocks.

I did, actually, citing my previous Comment here as an example.
