Honest side-by-side

Question	MATLAB	Validiti Maths
Annual cost per seat (commercial)	~$2,150 base + ~$1,000-2,000 per toolbox	$2,500 all-in
Toolbox model	Pay per toolbox — signal processing, stats, optimization, control, etc.	Single subscription. All math kernels included.
License check	Periodic phone-home to MathWorks license server	Local sealed binary. No phone-home.
Computation receipt	No structural receipt — outputs depend on your workflow	Signed receipt for every result. Reproducible by a third party.
Internet required?	For activation + many cloud features	No.
Where the math runs	Local for most things; some toolboxes call cloud	Entirely your hardware.
Defensibility in regulated work	Workflow + your notes	Signed receipt per computation — auditor / court / regulator ready
