Write this without a for loop?

for c= delaySamples+1:length(audioVec)
EchoVec(c)=audioVec(c)+z(c-(delaySamples)*EchoGain);
end

[Andrei Bobrov]

What is z, EchoGain?

[Michelle]

heres the entire code for my function

function EchoVec=soundEcho(audioVec,Fs,delay,EchoGain)
EchoGain=input('enter how loud echo should be:');
delay=input('enter in a delay value in seconds:');
delaySamples=Fs*delay;
z=[zeros(1,delaySamples),audioVec']; 
audioVec(length(delaySamples))=0;
for c= delaySamples+1:length(audioVec)
EchoVec(c)=audioVec(c)+z(c-(delaySamples)*EchoGain);
end
sound(EchoVec,Fs); 
end

when a third person runs your code (it is not possible to run) , nobody has the power to know what is in your computer

Michelle, if you feel that the question is unclear, then as you are the person who posted the question, you should be the one who clarifies it to make it more clear.

If audioVec is a column array and you ensure that (delaySamples)*EchoGain is a valid index:

c = delaySamples+1:length(audioVec);
EchoVec(delaySamples+1:length(audioVec))=audioVec(delaySamples+1:end)+z(c-(delaySamples)*EchoGain);
