i need to plot a sine wave of 1khz using sampling frequency. where am i going wrong? i need a correct representation of wave.

fs=10000;%sampling frequency
ts=1/fs;
t=0:ts:1-ts;
f1=10;
a=sin(2*pi*f1*t);
plot(t,a);

fs=10000;%sampling frequency

That would be 10 kHz . 1 kHz is 1000 samples per second.

i get it. i want to use f=1khz and fs=10khz. how do i set t (time vector) in order to plot a meaningful wave

[Walter Roberson]

fs=10000;%sampling frequency
ts=1/fs;
t=0:ts:1-ts;
f1=10;
a=sin(2*pi*f1*t);
plot(t,a);

That looks appropriate time to me. Your upper bound on your t is just before 1 (second) and you draw to 1 (second)
