To convert spherical coordinates (Distance, Azimuth, Dip) to Cartesian coordinates (XYZ), you can use the
sph2cart function in MATLAB. Here are the steps to do it:
First, make sure you have the necessary input arguments: Distance (r), Azimuth angle (azimuth), and Elevation angle (elevation).
sph2cart function with the input arguments:
[x, y, z] = sph2cart(azimuth, elevation, r);
This will calculate the Cartesian coordinates (x, y, z) based on the spherical coordinates (azimuth, elevation, r).
- The output arrays x, y, and z will contain the Cartesian coordinates for each corresponding input point.
It's important to note that the azimuth, elevation, and r inputs should have the same size, or sizes that are compatible. The azimuth angle is the counterclockwise angle in the x-y plane measured in radians from the positive x-axis, while the elevation angle is the angle in radians from the x-y plane.
sph2cart function supports various data types, including single and double precision, and also supports complex numbers. It can handle scalar inputs as well as arrays of any size.
If you need to convert a large array that doesn't fit in memory, you can use tall arrays, which are supported by the
sph2cart function. Additionally, this function can generate C and C++ code using MATLAB Coder, generate CUDA code for NVIDIA GPUs using GPU Coder, and run in a thread-based environment or on a graphics processing unit (GPU) using Parallel Computing Toolbox.
sph2cart function in MATLAB has been available since at least R2006a.
