loop while for where

i have this code but i do not knew how to run it

function y=quantr(b,x) delta=2./(2.^b); s=zeros(1,2^b); s(1)=-1+delta/2; for n=2:(2^b) s(n)=s(n-1)+delta; end y=zeros(size(x)); for k=1:length(x) p=1; while (abs(x(k)-s(p))>0.5*delta) p=p+1; end y(k)=s(p); end end

-----------------

x=-1:0.001:1; y=quantr(4,x); plot(x,y) xlabel('input'); ylabel('quantized output');

x=-1:0.001:1; %script file
y=quantr(4,x); 
plot(x,y) 
xlabel('input'); 
ylabel('quantized output');

function y=quantr(b,x) %function file
delta=2./(2.^b); 
s=zeros(1,2^b); 
s(1)=-1+delta/2; 
for n=2:(2^b) 
    s(n)=s(n-1)+delta;
end
y=zeros(size(x));
for k=1:length(x) 
    p=1;
    while (abs(x(k)-s(p))>0.5*delta) 
        p=p+1; 
    end
    y(k)=s(p);
end
end

Remark : function definition has to be at the end or in a separate function file with function name

see the edited code now

[ahmad ramadan]

i do not get it

[madhan ravi]

just download the file and run the code, if it works accept the answer so that others know the question is solved. Answer to your question "Do the function file and script file have the same name - no should be different name (function file has to have the same name as the function)"

[ahmad ramadan]

can you sceen shot where you put the code please

[madhan ravi]

download the attached file in the previous comment

Function definitions are not permitted in this context.

[madhan ravi]

function y=quantr(b,x) %function file
delta=2./(2.^b); 
s=zeros(1,2^b); 
s(1)=-1+delta/2; 
for n=2:(2^b) 
    s(n)=s(n-1)+delta;
end
y=zeros(size(x));
for k=1:length(x) 
    p=1;
    while (abs(x(k)-s(p))>0.5*delta) 
        p=p+1; 
    end
    y(k)=s(p);
end
end

save the above comment as quantr.m

[madhan ravi]

x=-1:0.001:1; %script file
y=quantr(4,x); 
plot(x,y) 
xlabel('input'); 
ylabel('quantized output');

[madhan ravi]

save the above comment as test11111.m and then run this file

[ahmad ramadan]

now its working, billions thanks

[madhan ravi]

Anytime :) accept the answer so that other people know the question is solved
