mergeImg(imgList) 说明: 将imgList的图像矩阵列表中的图像合并成一张大图像。 十、print2DMatrix 语法: print2DMatrix(matrix) 说明: 将2阶矩阵按照行和列方式打印输出每个元素 十一、cmpMatrix 语法: cmpMatrix(m1,m2) 说明: 比较两个矩阵是否一致,一致返回True,否则False。
Converts the matrix m into a list l. The split function is used to split the matrix into a list of vectors, with each vector containing the elements of a column. rep(1:ncol(m), each = nrow(m)) creates a repetition pattern to ensure that each column's elements are grouped together....
cugraph.structure.convert_matrix.from_pandas_edgelist(df, source='source', destination='destination', edge_attr=None, create_using=<class'cugraph.structure.graph_classes.Graph'>,renumber=True) 从边列表初始化一个图。在已初始化的 Graph 对象上调用此方法是错误的。源参数是源列名,目标参数是目标列名。
