Adding Columns & Rows

[Andy_C]

I promise I've done this before by accident, but now I can't find the keystroke anywhere in the help section.

Q: What's the keystroke(s) to add columns and/or rows to a matrix/array?

I get tired of reaching for the matrix toolbar every time I need to add a row.

Thanks.

ctl-M ... fairly mnemonic

Stuart,
I am fully aware of the ctrl-M option. That is clearly listed under the matrix toolbar section.

I'm looking for an operator that adds rows and columns without using the matrix toolbar at all, similar to how you can transpose using [ctrl] 6 without touching the matrix toolbar.

Got Anything?

Like I said, I am almost positive I've done this by accident on MC 13; I am now on MC 14.

If you are in an existing matrix, then click on a cell, then key [Ctrl] M. It will open the Matrix dialog and you can add additional rows and columns. If you just want rows, then put in 0 for columns.

That's what Stuart was telling you.

Yeah, I know.

Still no answer.

I'm just trying to avoid the matrix toolbar if possible. It's just quicker.

Would you want to go the calculator toolbar and click on the addition button every time you wanted to add? Probably not. The keystroke [shift]"+" is about a thousand times more fluid than using the addition button on the calc. toolbar. And, likewise with all the other quick-key operators.

Thanks anyway.

No

I'm not aware of any such keystrokes, and I would have thought one of the regulars would have noticed it and posted by now if there were one.

Indeed, I'd gone so far as to request this as a feature a couple of years ago http://collab.mathsoft.com/read?59760,12

[Andy_C]

Yeah, that's what I'm looking for... if it were available.

Oh well, maybe in the next version.

Thanks Stuart.

As a single keystroke: it would have to be near a function. Also, it is simple to combine the Matrix(m,n,f) with the replace(M,N,r,c). That is not demonstrated below. You can start doing quite a lot, simple. Not knowing the end purpose, and how much flexibility ???

Does it help ?

We are looking at matrices right now for a future release, so I'll add a quick keystroke for adding rows and columns into the discussion.

Multi-dimensional ones, I hope?

Thanks, Mona.

Do you mean something doing same (or more for Stuart !) as done in:

BTW, Mona:

a row operator like the actual col operator ... [row]. That will replace the double transpose actual method.

Yes, I want/need/demand.. the row extraction operator. We analyse lots of large images for effects along a row. Please can it be included.

This is from 2008 but Isn't this  SHIFT SPACE  and SHIFT ENTER ?

which means that the question was about real Mathcad (Mathcad up to version 15)

No - what you describe are the handy shortcuts available in Prime. Unfortunately changing the dimensions of an array was much more awkward in Mathcad than it is now in Prime. This actually is one of the few improvements in Prime over Mathcad. However, those few improvements in Prime do not outweigh the many missing features and other drawbacks. For example, speaking of matrices - scrolling in large matrices is extremely clumsy implemented in Prime compared to the standard scrollbars in Mathcad.

Thats the shortcuts in Prime, but not in real Mathcad!

Prime lags well behind the old Mathcad in very many respects, but the input and editing of matrices is one of the few improvements in Prime over Mathcad here. But speaking of matrices - scrolling in larger matrices is much worse implemented in Prime than with the classic scrollbars in Mathcad - in fact, it's just childishly playful and unreasonable in Prime.
