The basic function of the 2D drawing two-dimensional curve 1. plot function of the basic usage of the plot function calls the basic format: plot (x, y) x and y as a vector of the same length, were used to store the X and Y coordinates data.

cases in 0 = X = 2 pi range curve y= (2 - x). The procedures are as follows: x=0:pi/100:2*pi; y=2*exp (-*x).*sin (2*pi*x); plot (x, y)

Note: (1) when x, y is the same matrix, with X, y corresponding to the column elements for the horizontal and vertical coordinates were plotted, the curve is equal to the number of matrix columns. (2) when x is a vector, y matrix is one dimension and X dimensions, then draw the curve of a plurality of different colors. The number of curves is equal to the other dimension of the Y matrix, and X is used as mon abscissa of these curves. (3) the simplest call format of the plot function contains only one input parameter: plot (x).
