1 Verify that the plot function is a fitted function.

>> y = (x >=0)*1;
>> plot(x, y)
>> plot(x, y)

　　Effect:

2 plot(x) When x is a vector, draw a curve with the value of the x element as the ordinate and the serial number of x as the abscissa . When x is a real matrix, its serial number is the abscissa, and the
curve .
When x is an m×n matrix, there are n curves.

>> x = [1 2 3; 1 2 3; 1 2 3; 1 2 3]

　　

 

3 plot(x,y1,x,y2,…) draws multiple curves with common x elements as abscissa values ​​and y1,y2,… elements as ordinate values.
