how to improve calculation speed here? - Сообщения

Hi all,
I have two files here, one in smath, one in mathcad.
The mathcad file is calculated about 1000 times faster, does anyone have a tip how to speed up the .sm file?

By setting the formulas with the numeric optimization option switches from 29s to 19s. Still away from your expectations

16 more equally good improvements and it is solved...
Thank you Sergio

OFF topic of the speed, I don't understand your histogram.
Histogram take raw data from collection, ultimately to get a PDF.
Cheers ... Jean.

Hi Jean,
Sorry for the delay, unfortunately I found no time...
I have attached my histogram again, revised it a bit and commented it.
Actually I think it does exactly what it should, but I have to admit
that I don't know the exact definition of a histogram 8)
Histogram_JP.sm
And again about the speed: I played a little with my definition of "rnorm"
and come to the strange result that my vector is calculated fastest when
I calculate it in pieces of 20 elements.
I would be happy if a more experienced user could explain this to me.

Have a nice weekend!

Hi All,
I am new here, and facing similar problems. I intend to replace MathCad to an alternative solution due to PTC's pricing and support policy. I was very happy to find SMATH, and I started to test it. For short calculations it's a good alternative, but it seems very-very slow when long iterations are needed. I made a short loop both in Mcad and Smath containing just a few multiplications, and calculating it 1000000 times took ~0.2s for Mcad14, ~1s for Mcad8, and 32s for SMATH. So now I am a bit upset...

Care to share your .sm file?
Sometimes the are improvements to be made in how algorithms are structured.

In some instances, Smath is slightly faster than Mathcad 11.
However, almost not observable.
In other instances, Smath is horribly slow.
1 min Julia in Mathcad takes over 2 hrs in Smath
Same observation Fourier CoC ... and more.
Please, attach your document for Smath Community to doctor.

Your document does not open 'incorrect format'

SMath may not be fastest among them.
But some tricks can be applied.
It may improve calc speed slightly.

This is the file I made exclusively for speed check. There is no need to improve this calc by modifying it's structure, it is just for test purposes not a real task.
I started to use Mathcad in the last century (V6.0).
I made several calculations for example to simulate transient temperature rise of electrical rotating machines. I know there are better tools but I am familiar with MathCad that's why I am looking for a similar sw.

Attach your experimental data set.

And speed of your test code fails under SMath drastically.
But we all know these issues. For huge iterations SMath is not useful.
Anyone who plans to use this software should know this, SMath is a one-man show.
There are no paid programmers who can give all their time to SMath.
Only a handful of developers are included in writing and enhancing the code.
And they are doing this in their spare time, without any charge.
Maybe Andrey improve iteration speeds in future, who knows.
We can request something, it is up to Andrey include or improve that.
It is what it is, a free software which gives us mathcad interface.

"Anyone who plans to use this software should know this"
Yes, sure. I installed SMath 3 days ago, and now I am checking it's usability for my tasks.
And many respect to Andrey! In the last few days I also found many points where SMath is superior to MathCad.

I started to use Mathcad in the last century (V6.0).
Just for demonstration purposes, I've been able to increase the speed of this calc ~25% on my machine just by using vectorization rather than the for loop. It's still not near the performance you'd like, but just goes to show there are often things to be done to improve calculation speed. Vectorization isn't always possible in some algorithms, but when it is, it's generally faster.

In few days, imprudent to glorify the unknown yet.

You can't be more correct.
SMath may be behind than MathCad speed-wise.
But in terms of usability, features, visual aspects SMath is way better.
Just plugin support is a huge plus single alone.
