Hi
mtx_slice finally fullfills my need to get certain elements like
rows/colums of a matrix. might be nice to have this listed in the
matrix-help.pd down in the 'see also help for' section?
greets

hi
thanks to IOhannes indications i'm feeding my pix_mulitblob output into
the iemmatrix now. as long as there're enough blobs in the picture it
works pretty nice. but as soon as there're less blobs than given in the
argument to pix_multiblob i get:
error: $43: argument number out of range
error: $44: argument number out of range
without looking at the patch, i can tell you that this is because you
are actually _not_ using iemmatrix for handling the matrix.
instead your patch tries to manually parse the data using dollargs and
whatelse; which obviously fails if there are too few arguments (because
the matrix is too small)
indeed i'm using matrix - at least i'm trying to - but i might handle
the matrix data the wrong way. i could not find indications within the
matrix help on how to handle the data 'correctly' means without gettin
this error. so the way i solved it within the attached patch might be
stupid, but i'll appreciate any alternative!

for all the arguments of undetected blobs. and as soon as there's no
blob in the picture the pd-shell reports:
matrix : corrupt matrix passed
this indicates that you _are_ using iemmatrix here.
if no blobs are detected, pix_multiblob will output a somewhat illegal
matrix with zero rows (and a number of columns).
now iemmatrix complains that this is not a legal matrix.
probably putting a [mtx_check] helps to get rid of the error (or not)
no mtx_check doesn't change it
thanks for your help

do i do something wrong?
no.
