Matrix problem

[MagicHacker]

Does mathquill support matrix features?

[tmilev]

From what I understand, not the main project. However, the developers at learnosity have added support here:

https://github.com/Learnosity/mathquill/tree/matrix

The learnosity build had a tiny issue (I informed them of it, I suspect they will fix it soon). Until then, I've fixed the issue in my fork (master branch):

In case you have no experience with the npm build system (as was the case with me when I first started using mathquill), you can download the built files here:

Many thanks to the wonderful mathquill project!

@tmilev Sorry for asking this late, but I am not able to expand the matrix to other dimensions. I can not find any documentation for that either. Can you please advise?

[tmilev]

What do you mean by expand, do you want your users to be able to dynamically expand the matrices they type?

[kavibvaidya]

TL;DR: Yes.

So when I make the matrix, (say using \bmatrix), I get a 2x2 matrix. I was wondering how I can increase the dimensions of this matrix (increase cols and rows). Currently, I have a hacky way:

`
_.createBlocks = function() {

var content = prompt("Please provide the dimensions of the matrix");

dimensions = content.split("x");

num_rows = parseInt(dimensions[0]);

num_col = parseInt(dimensions[1]);

this.blocks = [];

for (var i = 0; i < num_rows; i++){

  for (var j = 0; j < num_col; j++) {

    this.blocks.push(MatrixCell(i, this));

  }

}

// this.blocks = [

//   MatrixCell(0, this),

//   MatrixCell(0, this),

//   MatrixCell(1, this),

//   MatrixCell(1, this)

// ];

};`

Note that I have some of your code in here to give you a context where I made changes. I got the idea from symbolab.

I was hoping to find a way to addCell directly as a user after I have made the matrix.

The only way I know how to do this is also hacky. I am not the original author of the code: to talk to the code's creator, try talking to the guys from this branch:

[]https://github.com/Learnosity/mathquill/tree/matrix

The one way I know to modify the matrix size is by doing:

currentMathField.write('\begin{pmatrix}&& \\& &\end{pmatrix}'); //creates a 2x3 matrix, all cells empty

currentMathField.write('\begin{pmatrix}&& \\& & \\ & & \end{pmatrix}'); //creates a 3x3 matrix, all cells empty

Thanks. Guess I will contact them or make a new function myself. I will let you know if I find a solution so that you can use that in your own project.

Shift-space adds a new column, shift-enter a new row.

Many thanks for the information!

Is there any plan for matrix support for the official mathquill?

[kavibvaidya]

I do not think there is. Online, I found a branch that supports matrices, however it did not allow mathquill functionality (like exponents and latex) inside the matrix. I added that myself by adding code to the JS file. I will try and find the file if I can and share it here.
