After removing some variables in the programm, Mathcad still behaves like a donkey not willing to surpass 5000 iterations creating new vectors <1000 entries long. The latest error message is about "accessing protected memory" indicating "corrupt memory". Does this refer to physical memory?

My configuration is 3 GB used memory with 32 bit W7.

Is there an easy way to get back som flexibility, using larger matrizes?

thanks

Umm, no, it didn't get lost. I got distracted halfway through by my wife asking me to yell at my 10 year-old who, in turn, got distracted by TV (or turned temporarily deaf by it) when asked to tidy up the bathroom after him! Posted without checking, I'm afraid. Mea Culpa.

Could you clarify what you mean by "5000 iterations creating new vectors < 1000 entries long"? Do you mean like the attached which runs a loop n times that creates a new vector of length m (erasing the old one) or creates n distinct new vectors or ...?

If you run the attached worksheet, do you get memory errors? I don't runnning it on a 32-bit Win 7 Ultimate with 4GiB RAM.
