How to create a 1xN structure?

[maryambrosino]

Hello everyone.
I would like to create a struct with size 1xN.

For example:
field1 field2
A 1
B 2
C 3
D 4
... ....

Which TinyMAt functions (or combination of them) can I use ?

You could use TinyMATWriter_writeMatrix2D_colmajor() ... see http://jkriege2.github.io/TinyMAT/group__tinymatwriter.html#ga710d61be33f483e62fe187c06bad5e38

Did it work for you? Can I close this issue?

Thanks you for support but it is not what I was looking for. This function doesn’t create a structure 1xN but a matrix. I need to create a multiple fields structure and each field should contains different type of data (string, double,int). Have you got anything alse to suggest me, please?

Hmmm ... let's see ... I think there are two options for that ... if I understand correctly:

1. There is a simple interface to write structs:

std::map<std::string, double> mp1;		
mp1["x"]=100;		
mp1["y"]=200;		
mp1["z"]=300;		
mp1["longname"]=10000*M_PI;		TinyMATWriter_writeStruct(mat, "struct1", mp1);		

This creates a struct with fields that contain one double each ... so this is very limited.
3. There is a low-level interface for structs that is very flexible:

TinyMATWriter_startStruct(mat, "struct1");
// ... use all other instructions here ... variables will be put as fields into the struct 
//... you can also use another start/endStruct pair to nest structs
TinyMATWriter_endStruct(mat);

There is also a similar interface for cell arrays ...

Does this help? If so, I can look for a better example and update the documentation within the next 1-2 weeks

Thanks but with the first option I don't resolve my problem. Instead, the second option is most efficiently but it don't resolve totally my problem. I would create a structure like this: [image: Schermata 2022-05-30 alle 09.05.34.png] Can you suggest anything else, please? Il giorno dom 29 mag 2022 alle ore 11:27 Jan W.
