类似地,如果array1与array2都是数组,那么表达式 array1.matrix()* array2.matrix()就是矩阵乘法。 下面是更高级的例子。表达式 (m.array() + 4).matrix() * m 表示矩阵m的每个元素都加4,然后转成矩阵, 再与矩阵m进行矩阵乘法,然后把结果赋值给m. 类似的,表达式 (m.array() * n.array()).matrix()...
Set the matrix to skew by sx and sy, with a pivot point at (px, py). SetSkew(Single, Single) Set the matrix to skew by sx and sy. SetTranslate(Single, Single) Set the matrix to translate by (dx, dy). SetValues(Single[]) Copy 9 values from the array into the matrix. ToArra...
