Line in matlab.

Ending vector value, specified as a real numeric scalar. k is the last value in the vector only when the increment lines up to exactly land on k.For example, the vector 0:5 includes 5 as the last value, but 0:0.3:1 does not include the value 1 as the last value since the increment does not line up with the endpoint. Plot two lines by specifying x and y as matrices. Use line to plot columns of y versus columns of x as separate lines. x = linspace (0,10)'; y = [sin (x) cos (x)]; line (x,y)Create a new matrix containing the RGB triplets for red, green, and blue. Then set the ColorOrder property to that matrix. The plot updates immediately with the new colors. mycolors = [1 0 0; 0 1 0; 0 0 1]; ax = gca; ax.ColorOrder = mycolors; MATLAB also cycles through different line styles in addition to colors.xline(___,Name,Value) xline(ax,___) xl = xline(___) Description. example. xline(x)creates a vertical line at one or more x-coordinates in the current axes. For example, xline(2)creates a line at x=2. example. …Description linecreates a line object in the current axes. You can specify the color, width, line style, and marker type, as well as other characteristics. The linefunction has two forms: Automatic color and line style cycling. line(X,Y,Z) MATLAB cycles through the axes ColorOrderand LineStyleOrderproperty values the way the plotfunction does.
