Python中的numpy.matmul函数用于计算两个矩阵的矩阵乘法。它的用法是numpy.matmul(a, b, out=None)。其中a和b是两个numpy数组。如果两个数组都是二维的,则进行普通的矩阵相乘操作。例如,如果我们有以下两个数组:
a = [[1, 0],
[0, 1]]
b = [[4, 1],
[2, 2]]
我们可以使用numpy.matmul(a, b)来计算它们的矩阵乘法,并得到以下结果:
array([[4, 1],
[2, 2]])
这里的结果是一个新的numpy数组,它是两个输入数组的矩阵乘法的结果。可以通过指定out参数来将结果存储在预先分配的数组中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
