Improve on TypeScript definitions to relfect support for multiple data types

Can’t one create a matrix of custom elements, e.g. objects, like {type:'something'}? I noticed that only numbers are supported

Thanks Jason for picking this up! Maybe it’s possible to define a MathScalar type, which is all types like number and Unit, except matrix types?

I’ve raised a new issue and hours later find this one (didn’t searched the correct key words).

I suggest to modify the @types/mathjs/index.d.ts on line 24

type MathArray = Number[] | Number[][];

to

type MathArray = MathType[] | MathType[][];

I’ve also noticed another potential typo on line 2974:

valueOff(): MathArray | Matrix;

should be

valueOf(): MathArray | Matrix;
