Specify or display systems of LMIs as MATLAB expressions
lmiedit is a graphical
user interface for the symbolic specification of LMI problems. Typing
up a window with two editable text areas and various buttons. To specify
an LMI system,
Give it a name (top of the window).
Declare each matrix variable (name
and structure) in the upper half of the window. The structure is characterized
by its type (
S for symmetric block diagonal,
G for other structures) and by
an additional structure matrix similar to the second input argument
lmivar. Please use one line
per matrix variable in the text editing areas.
Specify the LMIs as MATLAB® expressions in the lower half of the window. An LMI can stretch over several lines. However, do not specify more than one LMI per line.
Once the LMI system is fully specified, you can perform the following operations by pressing the corresponding button:

Editable text areas have built-in scrolling capabilities. To activate the scroll mode, click in the text area, maintain the mouse button down, and move the mouse up or down. The scroll mode is only active when all visible lines have been used.
