单位矩阵,即identity matrix,是一个方阵,其对角线上的元素均为1,其它位置上的元素均为0。单位矩阵在数学和计算机科学中具有重要的作用,其在矩阵运算和线性代数中起着关键的作用。下面我们将从几个方面来介绍单位矩阵的定义、特性、作用以及计算方法等内容。 一、单位矩阵的定义 单位矩阵通常用I来表示,它的定义如下...
3x3 identity matrix: I3 = ⎡⎢⎣100010001⎤⎥⎦[100010001]. 4x4 identity matrix: I4 = ⎡⎢⎢ ⎢⎣1000010000100001⎤⎥⎥ ⎥⎦[1000010000100001]. Verification of Identity Matrix If I is an identity matrix and A is any matrix of the same order, then by the definition...
Equation 7 shows an identity matrix 3x3, thus n=3 for this matrix. In that way, the trace is the addition of the elements of its diagonal, which is three elements of value 1 added with one another, and so, the trace is equal to 3. Therefore, the trace of an identity matrix is eq...
