How do I find multiple columns greater than a single column in MATLAB? -

i have single column vector average of other multiple columns (in vector). wish index when each element of matrix is greater average vector. able 1 @ time with:

idx = y1<y2

however if y2 matrix comes error. current solution on come is:

y1 = [y1;y1]

but rather inelegant , doesn't business relationship y2's of unknown sizes. regards

i think looking -

idx = bsxfun(@lt,y1,y2)

this create logical array of same size input matrix y2 1's elements in y2 greater than corresponding elements in y1 , 0's otherwise.

best thing bsxfun solve such problem takes care of expansion needed. so, have generic solution without querying sizes.
