This function does not work and gives the error in P=zeros(n) i don't understand why

function [P]=BULBP(x,n)
P=zeros(n);
for i=1:n
P(n)=P(n)+x(i)*Psat(i);

end 

end
end

Which error message do you get? Reading and considering them is a good idea in Matlab.

Answer 1

[Matt J]

Probably because you never define Psat.

Answer 2

[Azzi Abdelmalek]

What is Psat? Why are using 3 end?

function P=BULBP(x,n)
P=zeros(1,n);
for ii=1:n
  P(n)=P(n)+x(ii)*Psat(ii);   % what is Psat?
end

Answer 3

[Walter Roberson]

The code would give an error if n was negative or contained a fraction or an imaginary number.

Also note that if n is a scalar, then

zeros(n)

is the same as

zeros(n,n)
