data-types

Programming

SimLab supports these data types: double — Numbers and numeric arrays/matrices (default type) char — Strings enclosed in single quotes complex — Complex numbers (use i or j suffix, or complex(re, im)) logical — Boolean values (true/false, or 1/0) cell — Cell arrays that hold mixed types: {1, 'hello', [1 2]} struct — Structures with named fields: struct('name', value) symbolic — Symbolic math variables (declare with syms) tf/ss/zpk — Control system objects (transfer function, state-space, zero-pole-gain) Use class(x) to check the type of any value.

42, 3.14, 1e-6          % numbers (double)

[1, 2; 3, 4]             % matrix

'hello'                  % string (char array)

3 + 4i, complex(3, 4)   % complex number

{1, 'a', [1 2]}         % cell array

struct('x', 1, 'y', 2)  % struct

syms x                  % symbolic variable

x = 42

A = [1 2 3; 4 5 6]

'hello world'

z = 3 + 4i

c = {1, 'text', [1, 2, 3]}

s = struct('name', 'SimLab', 'version', 2)
