It's my 1st exposure to dsp on matlab ... please help. - ianl...@yahoo.com - Feb 1 8:06:42 2008



n = [-4:4];

y = 3*impseq(-2,-4,4) - 2*impseq(4,-4,4);
stem(n,x);

why do i get an error when i click run?

??? Undefined function or method 'impseq' for input arguments of type 'double'.

y = 3*impseq(-2,-4,4) - 2*impseq(4,-4,4);

Ian,
  impseq is a function. I think that is generating impluse sequence. Please check whether you
have defined it.
