Hi, just a short question about iemmatrix: is there a mtx_div? at least in pd-ext I cannot find it. and what is the difference between mtx_* and mtx_.*? or does mtx_* just not work with two matrices? marius.
Hallo Marius!
just a short question about iemmatrix: is there a mtx_div? at least in
hm ... I don't think so - just use mul !
pd-ext I cannot find it. and what is the difference between mtx_* and mtx_.*? or does mtx_* just not work with two matrices?
This is like in octave/matlab: .* means element wise multiplication, * means matrix multiplication.
e.g.: [ a ] * [ b ] = a*b + c*d [ c ] [ d ]
[ a ] .* [ b ] = [ a*b ] [ c ] [ d ] [ c*d ]

well, there is a [mtx_./]
since there is no division defined for matrices, there is no [mtx_/].

the help-file might be a good starting point to get the differences between all these objects.
in general, mtx-operations with a dot in the name (e.g. [mtx_.^]) work on the elements of the matrix whereas operations without a dot work on entire matrices. (this follows the matlab/octave conventions)
