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

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 file  Index.sm (9kb) downloaded 50 time(s).

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] Code:[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: ![2016-04-20 19_58_19-SMath Studio Desktop - [linear indexing.sm].png](/forum/resource.ashx?a=13686&b=2) Edited by user 20 April 2016 21:08:21(UTC)

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. Edited by user 20 April 2016 23:07:33(UTC)

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)".

I second this Originally Posted by: mikekaganski Andrey, thank you for this new build and for all your work! 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.

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 ...] Jean

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. |
