How to convert a BasicDBList or BasicDBOject

Hi,

i have a cell array from a MongoDB Json that I would like to convert to a matrix or vektor. The problem is that some of those cells are a "BasicDBList" or "BasicDBObject" containing multiple cells from the original Json. Is there a possibility to convert "BasicDBList"/"BasicDBObject" to double or a string array?

Thanks in advance

You can import the necessary MongoDB jars to MATLAB and then call the "toString" method of "BasicDBObject"/"BasicDBList", by doing this you can get the result in Java String type. Then you can convert the Java String to MATLAB char array as shown below:

str = java.lang.String('hello');
res = str.toCharArray'

If you want to convert the Java String to MATLAB string type, you can do it as shown below:

str = java.lang.String('hello');
res = string(str);

Please note that above shown conversion does not work on MATLAB R2016b and earlier versions. I hope this helps!
