我的数据邻接数组是
var g = [[10, 2], [15, 0], [18, 3], [19, 6], [20, 8.5], [25, 10], [30, 9], [35, 8], [40, 5], [45, 6], [50, 2.5]]
我的OpenCPU代码是
ocpu.call("centralization.closeness", {graph: g}, function(res){
// console.log(ocpu.seturl(res.output[0]));
$http.get("//public.opencpu.org/"+res.output[0]+"/json").success(function(data) {
console.log(data);
});
});
这给了错误
OpenCPU错误HTTP 400不是图形对象
通话中:centralization.closeness(graph = g)
最佳答案
centralization.closeness
需要一个图形对象而不是一个数组
建议:
将数组转换为邻接矩阵
使用graph_from_adjacency_matrix
将矩阵转换为图形。
将结果图传递给centralization.closeness
