Dear all
I know how to make 2d circle plot by polar function
I have a question to make a circular plate 3D without polar3d
Actually, I have to show the acoustical modes inside circular muffler.
but I don't know how to make a circular plate
For acoustic reponse, I got values in the Zdirection.
Here, I have already known, theta and radius.
theta = (pi/180)*[0:45:360]
theta = [0 0.7854 1.5708 2.3562 3.1416 3.9270 4.7124 5.4978 6.2832]
theta is represented by radian.
radius is 20cm
so [x,y]=pol2cart(theta, radius)
Now I knew x and y coordinate for each 9 point by theta.
and I know the Z value but this is not matrix
for 3D plot, [theta, radius, height]=cart2pol(x,y,z)
Here I have a problem
how to make 3D circular plot with this?
If I have to use a surf, this is not circular plate, the plot came out a rectangluar plate
polar 3D plot has totally different shape.
I wanna know that how to make 3D circular plot with this [theta, radius, height]
Actually, the thing I have to do show the sound pressure level at each theta point
Z will be sound pressure level.
please help me
