Is there away to do array push with mathjs matrix objects?

Question

Well, the title says it all. I am looking for a way to add rows or columns to an object created with

mm = math.matrix([[0, 1], [2, 3], [4, 5]]);
// can we do something like 
mm.push([0,1]);

I refer to the mathjs library here.

what is return type of *math.matrix*? or try like this mm = math.matrix(mm,[0,1]); — yugi, Sep 17 '15 at 12:59
try like this **mm = math.matrix(mm,[0,1]);** may be it will work — yugi, Sep 17 '15 at 13:04
@yugi that was my first intuition, too. But it's not working... can't believe this doesn't work. Rather feel like I am missing the obvious. — Matt Bannert, Sep 17 '15 at 13:18

i also checked their docs..they don't have direct push or any other functionality to achieve this.we have try our self in different manner to achieve that functionality .

1) convert to array and pass to matrix again

2) or add ur own method for matrix object

 math.push=function(e){
 // ur own code to implement the push  
 }

There is no push like function available. You can of course open a request for this in the issues section of the project.

The solution that comes closest is using the concat function:

mm = math.matrix([[0, 1], [2, 3], [4, 5]]);
mm = math.concat(mm, [[0,1]], 0);
// mm now contains: [[0, 1], [2, 3], [4, 5], [0, 1]]

The last number in the concat function specifies the dimension where to add the new data.
