clf

Create a line plot. Then, set the background color of the current figure.

x = linspace(0,2*pi);
y = sin(x);
plot(x,y)

f = gcf;
f.Color = [0 0.5 0.5];

Clear the figure using a call to clf. The function call deletes the plot. However, it does not affect the background color of the figure.

clf

Now, reset the figure properties and return the children of the figure. clf('reset') resets the background color to its default value.

f = clf('reset');
f.Children

ans = 
  0×0 empty GraphicsPlaceholder array.

Create two figures, each with a line plot. Set the background color of the first figure.

f1 = figure('Color','b');
plot(1:10)

f2 = figure;
plot((1:10).^2)

Clear the line plot from the first figure without resetting the background color of the figure.

clf(f1)

Now, reset all properties of the first figure.

clf(f1,'reset')

Create a figure with a white background. Then, create a surface plot.

figure('Color','w')
peaks

 
z =  3*(1-x).^2.*exp(-(x.^2) - (y+1).^2) ... 
   - 10*(x/5 - x.^3 - y.^5).*exp(-x.^2-y.^2) ... 
   - 1/3*exp(-(x+1).^2 - y.^2) 
 

Clear the surface plot from the figure and reset all figure properties to their default values. clf reset resets all properties of the current figure, except for the Position, Units, PaperPosition, and PaperUnits properties.
