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:

__________________________ *

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:

"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)

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:

cases(#,#,#,#,#,#,#,#,#,#,#,#,#)

You can also explore sum() function with a matrix in it:

sum(mat(#,#,#,#,#,#,#,#,#,9,1))

or just the system of equations feature:

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.

- even better! you can post an image of YOUR 25 pages long formula; You are correct that I am curious of this formula.

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