Note legendre_schmidt_all is in /GGF/ add the folders to Matlab path
Matmagglobal is a Matlab program package to calculate paleomagnetic field model
This program is translated from pymagglobal, nothing new is added, but rewrite it in native Matlab code.
Following model is included:
gufm1 arhimag1k pfm9k.1a HFM.OL1.A1 CALS10k.2 ARCH10k.1 LSMOD.2 GGF100k

Matmagglobal can be easily set up. Uncompress the Matlab code and add all the folders to Matlab path. Then, try (ggf)_try for more details.
Coordinate, unit, and timing range are provided in annotation
bpcsph = 【Br Bt Bp】 ,which is B_r (radial), B_θ (southward), and B_φ (eastward). The radius of Earth is set to 6371.2 km.
This program is a transition from pymagglobal, nothing now is added.
