i want to find out cheybsev type 1 filter average of graph FOR ORDER UPTO 50 . but one error is coming

g=1;

for n=0:50 %for initialising order

LBC=0;

Ln=0;

fc=50;

f=0:1:300;

x=f/fc;

e=0.5;

if n==0

T=0;

end

if n==1

T=x;

end

a=T.*T;

smr=1./(1+0.25.*a);

for i=2:n % for writing chebysev polynomial

T0=x;

T1=1;

T=(2.*x.*T1-T0);

T0=T1;

T1=T;

end

for fs=1:50 % less than cutoff frequency

if smr(1,fs)~=1

LBC=LBC+(1-smr(1,fs));

Ln=Ln+1;

else

end

LAB(1,g)=LBC/Ln;

g=g+1;

end

end

n=0:50;

plot(n,LAA)

ERROR:

Index in position 2 exceeds array bounds. Index must not exceed 1.

Error in c (line 35)

if smr(1,fs)~=1

Hello

The error message you're seeing indicates that the index fs in the line if smr(1,fs)~=1 exceeds the array bounds. This means that the value of fs is greater than the size of the array smr. The array smr is defined inside the loop for n=0:50, and its size depends on the value of n.

To fix this issue, you need to ensure that the size of smr is large enough to accommodate the index fs. One possible solution is to initialize smr outside the loop for n=0:50 with a size that can accommodate the maximum value of fs.

Hope this helps!
