WebMar 2, 2024 · A dot product is not really a scalar, but it behaves just like one. In math we call that an ISOMORPHISM. For every dot product result, there is a corresponding real number that you get by simply removing the brackets. All of the operations you do with the 1x1 matrix correspond to the same operations done with a real number.

Dot indexing is not supported for variables of this type.
