Ran in:
I have symbollic function, I'm plotting that function using fplot
syms y
U = y^2/2 - (3*y)/4;
yrange = [0,1];
fplot(U,yrange)
so i want to swap both axis in the plot, which means my yrange is in y-axis and U in x-axis?

fp = fplot(U,yrange);
plot(fp.YData,fp.XData)
grid on

You have three options:
  • you can solve U for y, taking caution because it will be multi-valued
  • you can use hg transform group and a rotation matrix to rotate the plot
  • you can use view() to change the camera angle
