I worked with SMath for about a year and identified three major flaws in SMath.
1. F9 instead of Ctrl+F9 (as in Mathcad) - recalculation of the entire document, and not individual statements, which were affected by the change
2. Lack of built-in or augmented limited optimization tools
3. Lack of ORIGIN. Often you want an array to start at element zero rather than the first element.
Your opinion?

Your opinion ? ............. You are not correct or partly correct on the counts [1,2,3] Under the hood, Smath is by design a global definition CAS. When you open a work sheet it scans top to bottom very fast. If you are at page 12 of a long document and in Auto-calc mode, at that last page ask for ln(1.23456789)= instantaneous. If you ask to plot ln(x), it recalculates the entire document because of the global definition mode and plot is a plugin. ............. You compose a piece of program, by default optimized symbolic. You best set symbolic/numeric from timing. augment/stack are by default symbolic, OK or not. If not correct, click for numeric. The last augment/stackin program are always correct. ............ We adapt ORIGIN 0 directly in the for loop suite. Good exercise for Valery, implement Convex Hull in Smath. Remember, Paul W. [Mathsoft Collab] produced most in ORIGIN 1. Take care Val ... Jean.

Your opinion? I think that it is more important for SMath to have a consistent user experience than to be similar to Mathcad. The bug tracking system shows a lot of proposals of what could be improved and most of it is independent of Mathcad behaviour. Feel encouraged to browse through the proposals and vote if you find something reasonable. Or add own requests and ask for votes. Here is a list of what spontaneously comes to my mind: - Numeric and symbolic evaluation should have visually distinct operators - The line operator should be displayed as a symbol in the Programming palette. - standard 2d and 3d plotregion. Here I really would recommend the Mathcad versions as prototypes. A benchmark for performance and features would be matplotlib. Maxima Draw is just a bloody workaround which most of the users don't even know because they don't mess around with third party software. - text format templates for section titles and the like. - help system which opens on F1. The interactive handbook was meant as a prototype for such a system but it is of low accessiblity for the users and. Your activity in the forum is proof that the SMath community benefits from the sanctions against Russia. Possibly, we will see also a boost in program development if that is not constrained to the eastern side of the iron fence. |

... many things work naturally index 1
Black background is [R,G,B] [1,1,1] ... not [0,0,0]

America imposed sanctions against Russia in order for Russia to become strong and help the US defeat China in the future.

In fact, I became aware of Smath by Fred, much before 2015.
On May 30, 15:00, PTC disabled all Mathcad Single User.
I then switched to Smath and perfectly Happy.
