Technique to create nested structures, MATLAB in Engineering

Technique to create Nested structures:

This technique is the most proficient. Though, the other technique is to build the nested structure one field at a time. As this is a nested structure with one structure inside of the other, the dot operator should be used twice here to get to the real x- and y-coordinates.

 

>> lineseg.endpoint1.x = 2;

>> lineseg.endpoint1.y = 4;

>> lineseg.endpoint2.x = 1;

>> lineseg.endpoint2.y = 6;

 

The nested structure has been once created; we can refer to various parts of the variable lineseg. Just typing the name of the variable represents only that it is a structure having two fields, endpoint1 and endpoint2, each of which is a structure.

>> lineseg

lineseg =

  endpoint1: [1x1 struct]

  endpoint2: [1x1 struct]

 

Typing the name of the nested structures will show the field names and the values within that structure:

>> lineseg.endpoint1

ans =

  x: 2

  y: 4

 

By using the dot operator twice will refer to a separate coordinate, for illustration,

>> lineseg.endpoint1.x

ans =

    2
