3d slice as a 2D image
I have a 3D volume and I have a plane crossing that volume. I have the plane equation (Z=f(x,y)) and so the normal to it. I want to analyse this plane not its projection. How can I obtain the rotated version (conciding with the xy-plane) of that plane with the values from the 3d volume ? I would be greatly thankful i... 11 Feb 2010 16:11

Transfering a mesh to MATLAB
Hi, I have a text file with three columns: x coordinate, y coordinate and the z value at point (x,y). I need to transfer this file to MATLAB and plot a 3D figure to show the z value at each point. How can I do this? thanks, ... 11 Feb 2010 15:03

Changing the axis on the compass plot?
Hello, I am using the compass plot to plot a circular data set but I have difficulties changing the axis of this plot. Specifically, I would like to remove some of the Axis point (say for example the 30 adn 60 degrees) and also I would like to change numbers (for example instead of 90 write 30). Does anyone have a... 11 Feb 2010 13:55

View Slice in 2D
I have a 3D data set and I have a plane slice in it. Z(x,y) or Y(x,z) I want to view this skewed plane as a 2D image. This can be done by rotation but I do not know how ? I have the plane equation and so the normal to it. ... 12 Feb 2010 05:28

Calculating the normal to a curve
Hi, I've just started using matlab and in order to gain experience I've been coding up some programs to perform simple tasks. To learn how to manipulate polynomials, I created a program to calculate and plot the normal to a curve at a given point. But it doesn't work. The resulting line isn't the normal at the point... 12 Feb 2010 05:28
