Not sure about the different syntax for linear indexing.
Does the "[" do something different?

Hello.

Not sure I understood your question.

Linear indexing for matrix was buggy in previous versions. In latest one it is finally fixed. Please see http://smath.info/bts/Issues/IssueDetail.aspx?id=129 for details.

P.S.: Yes, I've used "[".

Nice feature

if possible I suggest to improve the error message when the LHS doesn't fit the RHS (something like "wrong assignment pattern")

Andrey,
a[1 and a[2 do not need the "j" variable. In your screen shot, a[3=a[1,2 in my file and a[4=a[2,2
I've attached my fileIndex.sm (8 KiB) downloaded 88 time(s).

I understand nothing in here. You can create matrix as you wish [Smath 5346]

Linear indexing is a feature to identify an element of a matrix using a single number (base 1 index, starting from the top-left element, proceeding by columns and then by rows]

[1 2 3 4]
[5 6 7 8]
[9 .....]

Previously it was possible to use el(2) (one-index element) on matrices only in these cases:
- to set elements in column vectors:
- to get elements of column vectors;
- to get elements of row vectors:
- to get elements of matrices;

Assigning elements in matrices or row vectors wasn't possible:

In the meanwhile, a bug was introduced and it was possible to use el(2) in the LHS of assignments for any matrix, but in a wrong way.

Now it is possible to use this feature to get and set elements of any matrix:

So its the el(2) function!

That is why I was asking if Andrey was using "[" to define the matrix. I may have a use for the indexing which is why I was asking.

I have had an install problem with the 0.98.xxxx series versions, installer locks up. I need to go into task manager and kill the install screen after updating or installing fresh at this window.

If I put my mouse over this box, in Windows 7 (32 and 64), I get the mouse cursor to go to an spinning wheel. Program works fine in all installs otherwise.

Hurray! I finally found something to write to this thread!

OK, seriously, I'm really excited with this recent progress, and my constant flow of bug reports isn't meant to discourage Andrey; to the contrary, I wish this projest to prosper and flourish, and to be as problem-free as possible.

Andrey, thank you for this new build and for all your work!

EDIT: Oh, I feel so stupid! I wrote "Enter", while I must had written "Arguments delimiter (mine is semicolon)".

AND all of the developers for plugins, etc.

Mike, I cannot reproduce. I just updated on of my machines to this build. I go into the resulting matrix and the red cross bar "kicks out" into white space. However, on another existing file that was working correctly, it won't open

el(2) and "[" is actually the same.

Hello Collabs,

From a matrix result, you can do 3 things immediately besides
conventional matrix algebra [rotation, transpose, rotation, inverse ...]

1. drag/select, copy/paste element
2. extract indexed element
3. post process [arithmetic, function]
Be careful on [3] versus other CAS [Matlab, Mathcad ...]

Bingo! I'm beginning to be afraid of you

Just kidding!

Really, thank you very much for your help! I think it is just impossible for me to catch such issues (critical issues BTW) by myself.

Best regards!

You need to open Plugins tab in Extensions Manager, switch to Online Gallery and find & install all available updates there. After SMath Studio restart you will not see this error anymore.

I'm working on the wizard which will assist users to do this semi-automatically on every SMath Studio update as it is the most common issue now.

Best regards.

Wouldn't it be better to also check for available plugins updates and notify users of that regardless of event of main program update? To make it less intrusive, a toolbar informational icon could do the job, that, when active, on click would open relevant update window. By the way, current SMath update window is IMO too intrusive, too, and could be integrated into such informational system as well.

Why is the content creation date in MSI is shown 11/12/2009?

Actually, I needed this information when I noticed that this release was released twice: I have been notified by update manager and updated promptly, and haven't been notified again after that, but I started to see files that are "created with a newer SMath version" - 0.98.5953 (the same as mine), but last (fourth) part of version was greater.

Spotted matrix definition bug if using Clear():
File not found.File not found.

Also nested definition is not supported? In a form of

el(el(M,1,1),1,1):5
