this is part of the code but i get an error that " output argument J not assigned during call" can anyone help me see where im messing up
K = linspace(-20.5,13,501);
UpperBound = 1;
LowerBound = 0;
J = MYFunction(K)
function J = MYFunction(x)
N = length(x);
for n = 1:N
if x(n) <= -5.5
y(n) = .2.*x(n) + 4.1;
end
if (x(n) > -5.5 & x(n) <= 5.5)
y(n) = .08.*x(n).^2 + 5.42;
end
if x(n) > 5.5
y(n) = -.4.*x(n) + 5.2;
end
end

Probably your y is supposed to be your J
K = linspace(-20.5,13,501);
UpperBound = 1;
LowerBound = 0;
J = MYFunction(K)
function J = MYFunction(x)
J = x; % Initialize.
y = x;
N = length(x);
for n = 1:N
if x(n) <= -5.5
y(n) = .2.*x(n) + 4.1;
end
if (x(n) > -5.5 & x(n) <= 5.5)
y(n) = .08.*x(n).^2 + 5.42;
end
if x(n) > 5.5
y(n) = -.4.*x(n) + 5.2;
end
end
% Assign output y ==> J
J = y;
Not sure why you create UpperBound and LowerBound -- they aren't used anywhere.

Where in your MYFunction function do you assign any value to the variable J?
