looks great.

after posting it occurred to me that you might want your data files resemble the
matrix, rather than having a value per line.  :-)  assuming a justified (with
space chars) layout like:
2
123.0    4.56
  7.89  -2.0

you can use standard *NIX text processing tools to "massage" the data:
$ tr -s ' ' '\n' < myfile | grep -v -e ^$ | ./a.out

in English, 'tr' ("translate") converts spaces to newlines, the '-s' option
"squeezes" any number of consecutive chars into one, the grep looks for lines
which do not match an empty line.

looking forward to more on svd.  is it useful only for (vaguely)
spherical/elliptical shapes?


regards, jr.
