Hi everyone, I've got problem with while loop. I have this function with Xstart = 0.2 ; Xfinish = 2 ; deltaX = 0.2 and I need to solve it in smath studio, but while loop is processing forever and never ends. I'm doing something wrong, or it's a bug? Thanks! Images: https://postimg.cc/Q9mqWkKd Smath studio https://postimg.cc/KKZkgXPt Function I need to solve Edited by user 14 March 2020 16:35:01(UTC)

Is this what you need?  Edited by user 13 March 2020 23:01:26(UTC)

You can do the job using a while loop but it is just one option (perhaps not the most straightforward one).  loops.sm (11kb) downloaded 14 time(s).Edited by user 14 March 2020 12:10:02(UTC)

I need all X and all Y(x) values in the end, for Xfirst = 0.2, Xlast = 2 with step 0.2. y(0.2)= y(0.4)= y(0.6)= ... y(2)= And it should look something like this: x= 0.2 y= -0.6126 x= 0.4 y= 0.2173 x= 0.6 y= 0.7064 x= 0.8 y= 1.0721 x= 1.0 y= 1.3842 x= 1.2 y= 1.6771 x= 1.4 y= 1.9738 x= 1.6 y= 2.2924 x= 1.8 y= 2.6501 x= 2.0 y= 3.0639 I can type every y(x) in smath studio: https://postimg.cc/0bddLTqFBut, is it possible to do it with while loop?

What you are asking for is so restricted and useless for purpose ! Then you can: 1. start wherever [L] as long as computable your ln(,) 2. end wherever [N] 3. as fine step size [Δ] 4. algo style for infinite applications

I don't need any graphics, I just need to check the function with while loop. You sent example without while loop and without Xlast = 2, so is it possible to check this function with while loop, or no?

Pascal is pretty retarded these days for Engineering applications ! Years ago, Mathcad for Universities was pretty freaked. Better use Smath productive for studies & Engineering.  Golden ratio will be a life time productive Companion. As well as an advanced WhileLoop. Golden Ratio jmG.sm (40kb) downloaded 10 time(s).

If you need a step-by step feedback on the fly you can use breakpoints (menu of math regions) and the debugger window ("View" menu). You might have to store the intermediate results in a dedicated variable though, to don't look into the whole matrix at each step. Also you can use the function trace() and the output window, or you can build math strings using concat() and other functions, or maybe something more complex using the script region plugin by uni. loops-1.sm (31kb) downloaded 19 time(s).Edited by user 14 March 2020 19:40:33(UTC)

If you like my plugins consider to support SMath Studio buying a plan; to offer me a coffee: paypal.me/dcprojects |
