所以我有一个包含数据集信息的.CSV文件，数据似乎用JSON描述。我想用MatLab阅读它。一行示例（总共7000个）数据：
imagename.jpg,"[[{""name"":""nose"",""position"":[2911.68,1537.92]},{""name"":""left eye"",""position"":[3101.76,544.32]},{""name"":""right eye"",""position"":[2488.32,544.32]},{""name"":""left ear"",""position"":null},{""name"":""right ear"",""position"":null},{""name"":""left shoulder"",""position"":null},{""name"":""right shoulder"",""position"":[190.08,1270.08]},{""name"":""left elbow"",""position"":null},{""name"":""right elbow"",""position"":[181.44,3231.36]},{""name"":""left wrist"",""position"":[2592,3093.12]},{""name"":""right wrist"",""position"":[2246.4,3965.76]},{""name"":""left hip"",""position"":[3006.72,3360.96]},{""name"":""right hip"",""position"":[155.52,3412.8]},{""name"":""left knee"",""position"":null},{""name"":""right knee"",""position"":null},{""name"":""left ankle"",""position"":[2350.08,4786.56]},{""name"":""right ankle"",""position"":[1460.16,5019.84]}]]","[[{""segment"":[[0,17.28],[933.12,5175.36],[0,5166.72],[0,2306.88]]}]]",https://imageurl.jpg,
如果我使用Import functionlity / tool，我可以使用as作为分隔符分隔四个列中的数据：
图片文件名称，关键点，细分，图片网址

"[[{""name"":""nose"",""position"":[2911.68,1537.92]},{""name"":""left eye"",""position"":[3101.76,544.32]},{""name"":""right eye"",""position"":[2488.32,544.32]},{""name"":""left ear"",""position"":null},{""name"":""right ear"",""position"":null},{""name"":""left shoulder"",""position"":null},{""name"":""right shoulder"",""position"":[190.08,1270.08]},{""name"":""left elbow"",""position"":null},{""name"":""right elbow"",""position"":[181.44,3231.36]},{""name"":""left wrist"",""position"":[2592,3093.12]},{""name"":""right wrist"",""position"":[2246.4,3965.76]},{""name"":""left hip"",""position"":[3006.72,3360.96]},{""name"":""right hip"",""position"":[155.52,3412.8]},{""name"":""left knee"",""position"":null},{""name"":""right knee"",""position"":null},{""name"":""left ankle"",""position"":[2350.08,4786.56]},{""name"":""right ankle"",""position"":[1460.16,5019.84]}]]",
"[[{""segment"":[[0,17.28],[933.12,5175.36],[0,5166.72],[0,2306.88]]}]]",

但我试图使用该工具进一步分解数据。在corse中，理想的是将代码中的数据分开。
我希望有人能够指导我如何使用或需要使用的工具。我已经看到了其他问题，但它们似乎并不符合我的具体情况。
非常感谢!!

您可以使用以下命令structure1 = matlab.internal.webservices.fromJSON(json_string)
您可以使用以下命令json_string= matlab.internal.webservices.toJSON(structure1)

JSONlab就是你想要的。它有一个＆＃39; loadjson＆＃39;函数，它输入一个JSON数据的char数组，并返回一个包含所有数据的结构
