Each number is called an element of the array. Array operations allow operating on multiple numbers at once. ...

Invertible matrix
... inverse: an n-by-m matrix B such that BA = I. If A has rank m, then it has a right inverse: an n-by-m matrix B such that AB = I. A square matrix that is not invertible is called singular or degenerate. A square matrix is singular if and only if its determinant is 0. Singular matrices are rare in the ...

... The symmetry of the equations and diagrams suggest that inclusion and projection functions are two halves of a larger structure. They are, and later we’ll see how they’re ‘dual’ to each other. Because of that, we’ll use a different term and different notation for products of vector spaces. We’ll cal ...
