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']
