Hello,
in my Mathcad-worksheet I have i:=1..N, where N is very big (250000). Now I need in SMath also to calculate most formulas N times. In Mathcad I can take the Index (x_i) everywhere and so it calculate all N times. How can I solve this in SMath?
After calculating the worksheet I am not ready. I need to calculate all more times. So I must save results, where I need to append one number after every repeating. With wfile I don't know, how to append this one number? When I start next repeat, I must read all numbers and want to know, how many numbers I have? In Mathcad I have the function rows. Here it doesn't work. I can't separate my numbers by coma (...,...,...).
Many thanks for help and maybe link to example,
regards
Lothar W. |

What you want (and what is on my wish list) is range variables. Unfortunately, we do not have them in SMath. Thus, loops are required, see matrix chapter in the handbook. For writing and reading data, the functions WRITEBIN and READBIN from the plugin MathcadFileAccess might prove to be efficient and flexible for binary data files. They are documented in the function index of the pdf manual (signature link). The online manual does not yet cover data file handling. |

I will try anything, but for me has priority in this moment my working Mathcad 14. SMath I want for everyone because my results are important and interesting many people. Last ten repeats gave: 0.00729733118205 0.00729734592137 0.00729735783481 0.00729735727918 0.00729735497708 0.00729735234122 0.00729734389008 0.00729735045422 0.00729735045426 0.00729735431205 in my FSK.prn. Regards and hope for the version 1.0. Lothar W. |
