If you read the documentation for if, you'll see that when you write 테마복사 if expression then the expression has to evaluate to true/false, not a vector of true/false. There may still be a way to evaluate this in a vectorized manner, though. You have provided quite enough ...
B=fliplr(A)returnsAwith its columns flipped in the left-right direction (that is, about a vertical axis). B = fliplr (a) 返回 A, 其列在左右方向 (即关于垂直轴) 反转。 IfAis a row vector, thenfliplr(A)returns a vector of the same length with the order of its elements reversed. If...

前面学了很多的机器学习的理论知识了,但是纸上得来终觉浅,绝知此事要躬行,接下来几个视频一起来学习一些机器学习编程工具Octave的一些基础编码知识。 为什么要选择Octave? 吴老师在以往的机器学习教学中,尝试过很多种编码语言来进行实验,包括C++、Java、Python的Numpy,以及Octave。结果,吴老师发现使用Octave一类的高级语言...
