How can I execute the level enclosed between the two required functions in the plot?

Answer 1

[KSSV]

x = linspace(-1,2) ;

f1 = @(x) (x.^2-2*x+2) ;
f2 = @(x) -x.^2+6 ;

y1 = f1(x) ;
y2 = f2(x) ;

plot(x,y1,x,y2)

Thank you very much for drawing this diagram, can you tell me how to color between these two diagrams with the plot command?

[KSSV]

x = linspace(-1,2) ;

f1 = @(x) (x.^2-2*x+2) ;
f2 = @(x) -x.^2+6 ;

y1 = f1(x) ;
y2 = f2(x) ;

x = [x flip(x)] ;
y = [y1  flip(y2)] ;
patch(x,y,'r')
