Continuous plot(x,y) for discrete data points
显示 更早的评论
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)

for statistics, maybe you need to look at

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:
