How to pull-out coefficient from matrix simbolically

Hi all

Is`it possible to pull-out some coefficient or expression from matrix to show it in more compact (readable) form?

Here I want to change representation of matrix only.

Thanks in advance

Are you referring to something like this:

Else, provide an example of what you're looking for.

Success!

I don't think there's any way to do what you want. You can factor the matrix, but even in cases where that changes how one or more elements are displayed Mathcad does not pull the common factor(s) outside the matrix:

I'm not sure whether you want to automate the process or just manually adjust it.  If the latter, then you put the common factor in the units placeholder ...

Symbolic result doesn`t have unit placeholder in MathCAD 15.

Correct.

The symbolic processor isn't aware of/doesn't handle units, it treats them as (unknown, if applicable) variables.

So with symbolic evaluation Stuart's method doesn't help you. Numerically it does.

It depends upon the actual requirements and how general the solution needs to be.   If it's just a question of display, then it might, under given circumstances, be adequate, given then connection between the symbolic and numeric processors.
