I'm trying to make sign function that return sign of the input the problem is i can't make it return a vector when i type signt(4) i get the resultat but when i put a matrix i get an error
I'm trying to make sign function that return sign of the input the problem is i can't make it return a vector when i type signt(4) i get the resultat but when i put a matrix i get an error
function y = signt(x)
n=length(x);
i=0;
while(i<n);
if x<0
y(i)=-1;
else
y(i)=1;
end
i=i+1;
end
end
end

Begin ‘i’ at 1 and subscript ‘x’:
n=length(x);
i=1;
while(i<n);
if x(i)<0
y(i)=-1;
else
y(i)=1;
end
i=i+1;
end

Change it to:
n=length(x);
i=0;
while(i<n);
i=i+1;
if x(i)<0
y(i)=-1;
else
y(i)=1;
end
end
That works for vectors and scalars.
