在八度中，是否有像any（）的函数，但是用于行而不是列？

Question

In octave the built in function any() will return 1 if any element of the vector is nonzero.

so for a matrix

1 0 0 

0 0 0

0 1 0

it will return [1,1,0]

is there a function that will return the same but for the rows, instead of the column eg. return

1

0

1

I know I could do this with a rotation and then using the any() function, but I'm worried it will increase the time complexity.

Is there a built in function for this?

Answer 1

Octave's "any" function has an optional dimension argument. Set it to 2 to work along the second dimension.

any(m, 2)
