Issue with Support for Making Matrices Optional in Expressions

Issue Summary:

I am encountering an issue with the "react-equation" library, specifically related to the support for making matrices optional in the given expression. Currently, square brackets are accepted in the expression, but there seems to be no way of disregarding the presence of matrices when they are not needed.

Expected Behavior:

I expect that there should be a way to indicate that matrices are optional in the expression, and square brackets should not be enforced when they are not needed.

Actual Behavior:

The current behavior is that square brackets are always allowed, even when matrices are not intended to be used in the expression.

Thank you for your attention to this matter. Please let me know if there are any further details or clarifications needed.

I am a bit unsure about what you mean when you say "optional", but I'm gonna interpret it as "disallowed". If that is the case, and you simply want to get an error if anyone tries to use matrices, the answer is the same as the first part of my answer to you here: #31 (comment).
