Define a 5xN matrix such that each row of the matrix contains a sine wave with a frequency equal to the row number. (0 < t < 1).
I am doing the matrix of zeros thingie but it keeps telling me an error
t=0:0.001:1; x=zeros(5,length(t)); for i=1:length(t) x(i)=sin(2.*pi.*i.*t) end
can any body help ?

Try this:
t=0:0.001:1;
x=zeros(5,length(t));
for fi=1:5
for i=1:length(t)
x(fi,i)=sin(2*pi*fi*t(i));
end
end

You can avoid for-loop by simply:
t = 0:0.001:1;
f = 1:5;
x = sin(2*pi*f'*t);
