- Fixed issue when it was impossible to use trailing zeros option for zero results;
- Fixed issue when some functions are shown twice in the Insert Function dialog;
- Fixed critical error appeared on removing of empty cell from the vector/system/line functions if nested matrix/system/line exists there;
- Critical error appears on Region remove if the Region focused and located after the collapsed Area fixed;
- Fixed Region's selection error appeared sometime on fast mouse clicks;
- Fixed new Region painting issue if a Region added to the top left corner of the Worksheet;
- Fixed error of defining matrix elements using symbolic optimization;

Trying to use the pi product from the right-hand side palette gives me "product(" and not the pi product notation. Is this a bug? Also the sigma sum in the same palette gives me a sum(1), and not the sum(4) with the sigma notation. I´ve already read that: >Function sum(1) now built-in to the program; I think that sum(4) is more important than sum(1), in the right-hand side palette. Edited by user 19 May 2012 04:03:17(UTC)

Hello, Originally Posted by: Jarrinator  Trying to use the pi product from the right-hand side palette gives me "product(" and not the pi product notation. Is this a bug? It seems that it is a bug, unfortunately. Originally Posted by: Jarrinator

I´ve already read that:

I think that sum(4) is more important than sum(1), in the right-hand side palette.
I suggested to Andrey the introducing of sum(1) operator for its frequent use. I agree that now might be a bit confusing to choose the sum(4) from the function list, or to type sum( or choose summation from the palette and then to type four arguments. On the other hand there might be another confusing side effect when making sum(4) from sum(1). The summation could be made without brackets. Look at this simple example: x:mat(1,2,3,3,1)sum((el(x,i)+7),i,1,3)=27Contrary to the: sum(el(x,i)+7,i,1,3)=27This was made from sum( and putting four arguments: sum(el(x,i),i,1,3)+7=13This is made by choosing sum(4) and then adding 7 The sum(1) operator is useful and I am grateful to Andrey for introducing it, but unfortunately it seems some new side effects appeared with it.

Thanks for the explanation; about brackets, maybe they use some graphic space in the formulas, but they help us to avoid confusions when doing math operations with different expressions. Brackets are for math what units are for science and engineering. |
