简而言之,我想知道火炬中是否存在张量命令,它给出了张量满足某个标准的元素索引. 这是matlab代码,说明了我希望能够在火炬中做什么： my_mat = magic(3); % returns a 3 by 3 matrix with the number
这是matlab代码,说明了我希望能够在火炬中做什么：
my_mat = magic(3); % returns a 3 by 3 matrix with the numbers 1 through 9 greater_than_fives = find(my_mat > 5); % find indices of all values greater than 5, the " > 5" is a logical elementwise operator that returns a matrix of all 0's and 1's and finally the "find" command picks out the indices with a "1" in them my_mat(greater_than_fives) = 0; % set all values greater than 5 equal to 0
我知道我可以使用for循环在火炬中执行此操作,但是有一些等同于matlab的find命令可以让我更紧凑地执行此操作吗？
x[x:gt(5)] = 0
通常有x：gt：lt：ge：le：eq
还有一般：apply函数tha接收匿名函数并将其应用于每个元素.
