Magnetic fields of solenoids and magnets

Analytical calculation of the magnetic field of finite solenoids (which is also the field of cylindrical magnets) and cuboidal magnets

1) The file 'FieldBar.m' calculates the cuboidal magnet field with the formulas of Camacho & Sosa, Rev. Mex. E, E 59, 8-17, 2013 (see http://www.scielo.org.mx/pdf/rmfe/v59n1/v59n1a2.pdf), which have been corrected (see the documentation).

2) The file 'FieldSolenoid.m' calculates the cylindrical magnet (=solenoid) field with (corrected) formula of Callaghan & Maslen (1960) and Derby & Olbert, Am. J. Phys. 78, 229 , 2010 (see respectively https://archive.org/details/nasa_techdoc_19980227402 and https://doi.org/10.1119/1.3256157). See details in the documentation.

3) The file 'PlotField.m' plot the magnetic field in various cases, for cylindrical magnets (=solenoids) and cuboidal magnets.

WARNING/REQUIREMENT: the included files whose name start with 'Elliptic' calculate the needed elliptic integrals (these files are actually the functions I have released at https://fr.mathworks.com/matlabcentral/fileexchange/51989-maple-elliptic-integrals), by relying on 'Elliptic_Integrals.zip' by Thomas Hoffend, which has to be downloaded at https://fr.mathworks.com/matlabcentral/fileexchange/3705-elliptic_integrals-zip

[Alternatively, 'Elliptic Integrals' by Moiseev Igor (https://fr.mathworks.com/matlabcentral/fileexchange/8805-elliptic-integrals-and-functions?s_tid=srchtitle) can be used by commenting/uncommenting 2 lines in the files whose name start with 'Elliptic']
