see, seeiv (Mu Analysis and Synthesis Toolbox)

Display a SYSTEM or VARYING matrix

Syntax

see(mat,iv_low,iv_high) 
see(matin) 
seeiv(mat)

Description

see displays the A, B, C, and D matrices of matin for a SYSTEM matrix or the independent variable and the matrix at that variable if matin is a VARYING matrix. iv_low and iv_high are the optional range of the independent variables to be displayed. see displays the matrix itself if the input is CONSTANT.

seeiv displays only the independent variable of the input VARYING matrix mat. An error message is displayed if the input matrix is not a VARYING matrix.

Examples

The see command displays any type of matrix. An example of its use for SYSTEM and VARYING matrices follows:
