When using plot(x,y) function, [say for example x = 1X20 matrix and y=sin(x), which means that there are only 20 data points), matlab plot comes out to be a continuous one. Is this always the case? I just started using matlab.

Select the functions to represent the graph of a continuous and a discrete function.

You can use plot for continuous plot, or stem function for discrete plot. You can also use scatter function
Example
x=0:10
y=sin(x)
plottx,y);
figure
stem(x,y);
figure
scatter(x,y)

plot is just connecting the points with lines. If you don't want this, you can specify the marker. For example, for a red *
>> plot(0:0.1:2*pi,sin(0:0.1:2*pi),'r*')
And for more info:
doc plot

Thank you, Sean. That was very helpful. I tested with and without markers (default). Works great!
