A collection of tools to speed up digital note-taking in scientific and mathematical fields.

Use matex_gen facilities in vectex_gen

Vectors are matrices with 1xN (columns) or Nx1 (rows) dimensions.
It might be clever to extend the FullMatrix or Matrix classes and reuse the code.

Should vectex_gen share no code with matex_gen in order to be completely independent?

Matex improvements

Add features:

• triangular upper and lower
• identity matrix
• diagonal
• from list of elements (CLI)

Index separation on subscripts

When generating big matrices with numerical indexes (no symbolic ones), it becomes difficult to distinguish the column and row index.

A space or comma might be inserted in the indexes subscript. Optional and enabled with a command line parameter.

Custom numerical algorithms

When a numerical matrix is created, the product of the indexes is taken as the numerical value for the cell with the proposed edits #6. This is not always the case.

A custom numerical algorithm* might be specified and used in the elementAt method, such as sum, difference etc.

*an expression involving i and j

Natural language CLI

In order to speed up even more the note-taking process, a natural language command line interface can be added.

When trying to follow the teacher, it might be difficult to lookup the command line argument help and get the wanted matrix at first try. A natural language interface enables a faster than ever approach to matrix generation.

Let's say I want to generate a generic MxN upper triangular matrix with "e" as symbol. With the current CLI the parameters would be:

./matex_gen.py -r m -c n -g -s e triu

which is hardly readable.

A natural language formulation might be:

./matex_gen.py generic mxn triu e

or better

./matex_gen.py generic mxn triangular upper matrix e

Custom compact rows/columns number

With #6 the number of columns and rows when selecting --compact-rows or --compact-columns was abstracted as a global variable.

An additional command line parameter may define a new value for those parameters.
