4.instance

by using the instruction "polt(X, Y, S)", we can plot points and lines with the types listed above.  in "polt(X, Y, S)",X and Y are vectors, S is a string formed of elements listed above. For example, when S = 'o--', it means that the symble for points is circle, and the line format is dashed.

conduct the instructions：

>> x = [1:1:10];
>> y = [2:1:11];
>> plot(x, y, 'o--')

we can get figure below:
