sphere_to_cart (MathScript RT Module Function)
Owning Class: basic
Requires: MathScript RT Module
Syntax
[x, y, z] = sphere_to_cart(a, b, c)
Legacy Name: sph2cart
Description
Converts spherical data into 3D Cartesian data. This function works element-wise for matrices.
Inputs
| Name | Description |
|---|---|
| a | Specifies the azimuthal angles, or the angles measured from the x-axis to the data points projected in the xy-plane. a is a matrix. |
| b | Specifies the elevation angles, or the angles measured from the xy-plane to the data points. b is a matrix of the same size as a. |
| c | Specifies the radii. c is a matrix of the same size as a. |
Outputs
| Name | Description |
|---|---|
| x | Returns the x-coordinates. x is a matrix of the same size as a. |
| y | Returns the y-coordinates. y is a matrix of the same size as a. |
| z | Returns the z-coordinates. z is a matrix of the same size as the smallest of a, b, and c. |
Details
LabVIEW computes a, b, and c using the following equations:
x = c.*cos(a).*cos(b)
y = c.*sin(a).*cos(b)
z = c.*sin(b)
Examples
[X, Y, Z] = sphere_to_cart(1, 1, 1)
