vector length problem error

1. Compute the DFT of a sinusoidal signal with six frequencies: ω1=0.1*pi; ω2=0.2*pi; ω3=0.3*pi; ω4=0.4*pi; ω5=0.5*pi; ω6 =0.6*pi and plot the magnitude spectrum .for this qn tried many time but delimiter and vector error occurs.

here is my code:

w1=0.1*pi;
w2=0.2*pi;
w3=0.3*pi;
w4=0.4*pi;
w5=0.5*pi;
w6=0.6*pi;
t=0:1000;
x=sin(w1*t)+sin(w2*t)+sin(w3*t)+sin(w4*t)+sin(w5*t)+sin(w6*t);
y = fft(x);                               
m = abs(y);
c=2*pi*((0:length(y)-1)/2);

f = c/length(y);
plot(f/pi,m(1:length(y)-1/2));

w1=0.1*pi;
w2=0.2*pi;
w3=0.3*pi;
w4=0.4*pi;
w5=0.5*pi;
w6=0.6*pi;
t=0:1000;
x=sin(w1*t)+sin(w2*t)+sin(w3*t)+sin(w4*t)+sin(w5*t)+sin(w6*t);
y = fft(x);                               
m = abs(y);
c=2*pi*((0:length(y)-1)/2);
f = c/length(y);

n = round(length(f)/2) ; 
plot(f(1:n)/pi,m(1:n));

I want all vector length same @KSSV

[Image Analyst]

@MICHKEL ANGLO J, yes, you've got that. All the vectors are 1x1000. If youi don't agree, which are you saying have different length(s)?

I mean line drawn (length of x to y axis)@Image Analyst. I got the output now.

w1=0.1*pi;

w2=0.2*pi;

w3=0.3*pi;

w4=0.4*pi;

w5=0.5*pi;

w6=0.6*pi;

t=0:1000;

x=sin(w1*t)+sin(w2*t)+sin(w3*t)+sin(w4*t)+sin(w5*t)+sin(w6*t);

m = abs(x);

c=2*pi*(0:1000);

f = c/1001;

n = round(length(f)/2) ;

plot(f(1:n)/pi,m(1:n));
