ndims (Control Design and Simulation Module, MathScript Function)
Member of the info class.
Syntax
dim = ndims(SysIn)
Description
Calculates the number of dimensions of a system model. The number of dimensions also is the order of the model.
Inputs
| Name | Description |
| SysIn | Specifies a linear time-invariant (LTI) model in transfer function, zero-pole-gain, or state-space form. |
Outputs
| Name | Description |
| dim | Returns the number of dimensions of the SysIn model. dim is an integer scalar. |
Examples
A = [-1, 0.1; 0.2, -2]B = [0; 1]
C = [1, 0]
D = 0
SysIn = ss(A, B, C, D)
dim = ndims(SysIn)
