Hi everyone.
I am trying to run a signal processing code provided by others, which is to plot the curve of digital filter. But it gives me the following error
"
Undefined function ’eml_lib_assert’ for input arguments of type ‘char’.
Error in freqz (line 15)
eml_lib_assert(nargin>=1,’signal:freqz:notEnoughInputs’,’Not enough input arguments.’);
"
The original code is as follows
"
num=[0.0528 0.797 0.1295 0.1295 0.797 0.0528];
den=[1 -1.8107 2.4947 -1.8801 0.9537 -0.2336];
[z,p,k]=tf2zp(num,den)
figure(1);
zplane(z,p)
m=256;
w=[1:pi/m:pi];
%h=freqz(num,den,w);
[H w]=freqz(num,den);
magH=abs(H);
figure(2);
plot(w,magH);
xlabel(‘omega/’); ylabel(‘|H(e^j^omega)|’); grid;
“
The person who provided this code mentioned to set path in MATLAB, but I have no clue how to properly set the correct path. The matlab version I am currently using is R2013b with the Signal Processing Toolbox version 6.20.
Any insights or ideas will be greatly appreciated. Thanks.Hi everyone.
