ejml - Using EJML, is there a quick way to find mean of columns of a matrix?

Question

Was looking for a function which returns a one diamensional SimpleMatrix giving the mean.

Answer 1

不幸的是，没有内置函数可以做到这一点。不过，这应该可以解决问题：

SimpleMatrix ones = new SimpleMatrix(1,10);
ones.set(1);
SimpleMatrix m = SimpleMatrix.random64(10,20,-1,2,new Random());

SimpleMatrix sum = ones.mult(m);
SimpleMatrix mean = sum.divide(10);
