MFeval (Magic Formula evaluation) has been created to provide a robust way to evaluate Magic Formul tyre models.
The toolbox contains the function with the same name (mfeval.m) used to evaluate tyre property files with the Magic Formula 5.2, 6.1 or 6.2 equations. A tyre property file (.tir) contains the magic formula parameters that define the tyre's force and moment characteristics.

Zip Toolbox	12 Mar 2021	4.3.1	readTIR can read files that are delimited with Line Feed (LF) or Carriage Return (CR) and Line Feed (LF) Radius calculation for MF6.2 compatible with the C code compiler
Toolbox Zip	26 Jan 2021	4.3.0	◾ Warning in the Mx formulation if parameter sets QSX1 to QSX11 and QSX12 to QSX14 are non zero ◾ Fixed bug in the radius calculation using MF5.2 ◾ Faster radius calculation for MF6.2 (secant method) ◾ Faster CPI Simulink model implementation
Toolbox Zip	2 Dec 2020	4.2.0	See in the comments
Toolbox Zip	29 Sep 2020	4.1.1	Fix small error on version number
Toolbox Zip	29 Sep 2020	4.1.0	See the comments sections or the release notes on the documentation for more information
Zip Toolbox	17 Mar 2020	4.0.0	MF-Tyre 5.2 equations have been implemented for backward compatibility
Toolbox Zip	9 Dec 2019	3.0.0	MF-Tyre 6.2 equations have been implemented. In 6.2 the loaded radius model is improved with camber dependencies. See the documentation for more information
Zip Toolbox	23 Oct 2019	2.3.0	Slip stiffness (Kxk) is now output number 30 In STI vertical damping forces only actuate if the tire is in contact with the road In STI the Slip Angle calculation has been updated to use the transformation matrix
Toolbox Zip	1 Oct 2019	2.2.1	Road friction can be passed as input to STI and CPI interfaces Unnecessary zero crossing detection have been disabled Fx and Fy filters moved to reside inside Switch dynamics mode In Mz calculation, Gyk_sub0 is now calculated after Fyo_sub0
Zip Toolbox	3 Jun 2019	2.2.0	Road position implemented in STI Road velocity implemented in STI Some MATLAB Function blocks have been replaced with inbuilt Simulink blocks The switch case to select the dynamics mode in CPI is done upstream to avoid unnecessary calculations ...
Zip Toolbox	15 Feb 2019	2.1.1	◾ Simulink Library updated to work with variable solvers. ◾ Simulink memory blocks have been replaced with low pass filters with a pass band frequency of 15 Hz ◾ coefficientCheck inputs have been updated to be compatible with MFit
Toolbox Zip	19 Nov 2018	2.1.0	Simulink Library updated to be more robust and consistent (STI interface depends on CPI interface) All Simulink blocks and demos are saved in MATLAB 2017b Advance user guide completed: including a demo showing how to fit a model
Zip Toolbox	15 Nov 2018	1.4.0.0
