Explore libstruct Objects

Open Live Script

This example shows how to display information about and modify a libstruct object, c_struct.

Load the shrlibsample library containing the c_struct definition.

if not(libisloaded('shrlibsample'))
    addpath(fullfile(matlabroot,'extern','examples','shrlib'))
    loadlibrary('shrlibsample')
end

Create the libstruct object. Object sc is an instance of a MATLAB® class called lib.c_struct.

sc = libstruct('c_struct')
sc = 
  c_struct with properties:

    p1: 0
    p2: 0
    p3: 0

Set structure field values.

set(sc,'p1',100,'p2',150,'p3',200)

Display field values.

get(sc)
    p1: 100
    p2: 150
    p3: 200

Modify values using MATLAB field structure syntax.

sc.p1 = 23;
get(sc)
    p1: 23
    p2: 150
    p3: 200
