Questions tagged [matlab-struct]

For questions about the MATLAB structure datatype.

A structure is a datatype in MATLAB. It is different from cells and arrays in that it uses field names, and within fields one can store other data, also of type struct, cell, array, etc.

MathWorks has a tutorial on accessing data in a structure array.

The basic function to create one is, among others, struct.
