These are the locations in the matrix in which the logical expression is true, in this case, any location greater than 12. Now the expressionA(A > 12) extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column ...

'abs'— Sort rows ofAbyabs(A)whenAis real or complex. If a column ofAhas elements with equal magnitude, then useangle(A)in the interval (-π,π] to break ties. Output Arguments collapse all Sorted array, returned as a column vector or matrix.Bis the same size asA. ...
1. Establishment of the matrix 接下来我们将利用上面提到的三种方式建立一个三阶矩阵,其代码如下图所示: Next, we will build a third-order matrix using the three ways mentioned above, the code of which is shown in the following figure:
