how do I swap both axes in the current plot

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?

syms y

U = y^2/2 - (3*y)/4;
yrange = [0,1];

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
