[英]How to find the elements of a matrix > 0 in Matlab?
我很好奇-是否有单个Matlab命令返回Matrix中大于0的元素?
The following code returns all positive elements of matrix A
: 以下代码返回矩阵
A
所有正元素:
A(find(A > 0))
or in short form as proposed by Gunther Struyf: 或Gunther Struyf建议的简写形式:
A(A > 0)
The find function will return the indices of elements that are not zero. find函数将返回不为零的元素的索引。
ind = find(A > 0);
is what you're looking for... 是您要寻找的...
或为此目的专门设计的命令:“ nonzeros”
nz_A = nonzeros(A);
