I would like to use "find" with some set functions, because a for loop takes
too much time. For example, I have a large array aa (100000,10) where each
row has 10 numbers. I want to use the complement function to find all rows
that contain the values [12 54 77]. This code is too slow:
for ix = 1:rows(aa)
if (columns(complement (aa(ix,:), [12 54 77])) == 0)
...save ix...
endif
endfor
I would like to wrap this in a find function, but I don't know the syntax
for this.
find(columns(complement (aa(:,:), [8 43])) == 0); does not work.
Thanks
