MATHCAD Array Operation Doesn't Work for Long Vectors

Click For Summary
SUMMARY

The forum discussion centers on issues with performing array operations on long vectors in MATHCAD, specifically when vectors exceed 9 elements. Users report that attempting to operate on vectors of 10 elements or more results in an error indicated by a "black dot" output. One user suggests that the problem may be related to display settings rather than the array operation itself. To resolve the issue, sharing the worksheet for further analysis is recommended.

PREREQUISITES
  • Familiarity with MATHCAD software
  • Understanding of array operations and vector mathematics
  • Knowledge of troubleshooting display issues in software applications
  • Ability to share and zip files for forum discussions
NEXT STEPS
  • Investigate MATHCAD's documentation on array operations for vectors
  • Learn how to troubleshoot display issues in MATHCAD
  • Explore MATHCAD forums for similar user experiences and solutions
  • Practice sharing and zipping files for collaborative troubleshooting
USEFUL FOR

This discussion is beneficial for MATHCAD users, mathematicians, and engineers who are working with vector operations and encountering display or operational issues in their calculations.

Hello,

I am looking for some advice. I'm trying to perform array operations on vectors in MATHCAD. I am able to do it for vectors and matrices that have both dimensions that are 9 units or shorter. Anything that is 10 units or longer (ex, a vector with 10 elements) outputs a result such as:


log(Y)→ = black dot black dot

→ is the vectorized arrow.

Has anyone had a similar issue? If so, what can I do to fix it?

Thanks!

Unfortunately, without seeing your worksheet (or even a picture), it's difficult to say. I regularly apply the vectorize operator over millions of elements. If you could post the worksheet (you'll have to zip it before the Forum will allow you to download it), that will help get to the bottom of the problem.

Consider the possibility that it could simply be a display issue...I would look into the help, the search option and search for display results or matrices or something ... or go to Options or something along those lines...somewhere
