Hi All

I dont know how to do like this link , to gather my data neatly in one paranthesis , I dont know it's name


http://en.smath.info/forum/yaf_postst7446_About-Units.aspx

It's a system... Type sys and then press the TAB key; it is available even as last element in the "Functions" toolbox (right side of the canvas); using the "argument separator" key (that commonly is comma or semicolon, depending on your settings), you can add more lines.

Thank you very much , but I can not add more lines correctly, it seems that separator is not active

I cannot check right now but I've not noticed issues recently. Go to tools > options and check if you are using the right character.

In a single column vector, you can add place holder(s): type coma on the last
entered value. If you have too many : press Backspace. If you have constructed
an array [matrix], you need some tool to add/remove cols/rows. These tools are
available in the attached "Matrix Treasury".

Cheers, Jean

Ok here is the image, attention that in the below equations , I gave up making a system, I have just written down the 4 last equations ,only for the input data it worked well

Please notice that you cannot have results individually next to each subexpression in system: the system is one global expression that contains others, and only top-level expression's result may be displayed.
Also notice, that for systems (or matrices as well) of heterogenous elements, you cannot specify units, and even simple units (like Pa) will be displayed as their internal representation of base units of length, time, mass etc.

For homogenous structures, you may specify the common unit in the rightmost unit placeholder, as usual

One more thing: when posting screenshots displaying a question, it's generally a good idea to accompany it with an .sm file, so that others could avoid re-typing everything trying to reproduce.

What else to complete a project ?

Thank you so much for your perfect answers
