I've tried using the "norme" function -- the function that calculates the Euclidean norm of a vector (or matrix) -- and can't get it to work. For example, when I try:

s:mat(1,2,3,4,5,5,1)
norme(s)=

It won't calculate the Euclidean norm. Instead I get this strange message:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Not a big deal, since you can define your own "norme" function, e.g.,

NormE(F):line(nn:length(F),sqrt(sum((el(F,k)^2),k,1,nn)),2,1)

but, if it's listed in the "function" collection, it'd be nice to have it working properly.

That is strange...

The norme() does not work on the laptop with Win7 "error: Atempted to read or write protected memory..." - but it does works at the desktop with WinXP.


[MATH=eng]s:mat(1,2,3,4,5,5,1)[/MATH]

[MATH=eng]norme(s)=7.4162[/MATH]

same error with Win7 desktop.

enorm() seems to work now (with 0.96.4884). The workaround from the customFunctions plugin is switched off here, as the dynamic assistant (invoked by F12) shows.

Good, I'll disable the customFunctions workaround
