Hello Everybody,

I have a small practical question:
How to split a long line (formula) on two or more lines.

I think that the subject was explained somewhere but I’m not sure about.

I know the primary solution of allocation variable names for the parts of the formula, but…

Thanks for your help.
Ioan

If your formula is piecewise composed of ± pieces, stack those pieces.

Write an expression, put the cursor to where you want a line break and press Ctrl-Enter.
This works only once in a formula, not inside results and not inside brackets.

Greetings,

You could also word-wrap your formula:


__________________________ *
SMATH_wordWrap_Math.jpg

where the 'string' uses newline characters to force on the next line (\000A\ is the special code SMath uses, just copy/paste this and it will word-wrap the string). You can copy and paste the following into your worksheet:
Code:
"a+b+\000A\0+c+d+\000A\0+e+f"


  • write your math expression as a 'string'
  • pass that value through the str2num() function; it will be evaluated





*There is an issue:

I have yet to see such long formula from native Engineering.
If your formula results from symbolic expansion... try maple.
For curiosity and help, show an image of that formula.
I have a 25 pages long formula ... Nothing can be done !

Thank you all for your kind answers.:'(
In fact, I looked more to something like in Mathcad: (without limitations as mentioned by Martin - only one shot)
https://www.mathcad.com/...moves%20down%20a%20line.
Best Regards,
Ioan

Greetings,

I have used Mathcad's split feature as well and I can understand your plight. Keep in mind some other alternatives to present your data. For instance, you can use the a cases() function to organize your criteria/responses in a compact manner:
Code:
cases(#,#,#,#,#,#,#,#,#,#,#,#,#)


SMath_alternativesToWrap.jpg


You can also explore sum() function with a matrix in it:
Code:
sum(mat(#,#,#,#,#,#,#,#,#,9,1))


or just the system of equations feature:
Code:
sys(#,#,#,#,#,#,#,#,8,1)


Finally, you can just select your math statement and decrease the font size such that your equation will fit on the page. I have resorted to decreasing the font down to font size [2] in order for my matrix/tabulated data to fit on one page width; it served my purposes. [2023-09-28]


Also: Jean, Thank you for the good laugh! I always enjoy your litany of responses.


May this be of Good Help;

I won't show that f(x,y) symbolic expansion.
Always nice to read you Kenny ... Jean.
