in an old m file I used the function ltipack.checkABCDE for lti model.
This function is not recognized by 2024 Matlab version.
I would like to know what replaced this function.

Hi Yehuda,
May i know which version were you using before where the function was working fine and maybe possible, share that part of 'm' file where the function is used?

It was old - before 2016. But I canged the ss_y function to ss function and it solved my problem.

Hello Yehuda
From what I understand, you are trying to useltipack.checkABCDEfunction in a MATLAB file that was running in an older release but is not supported in R2024a.
Based on my investigation, thecheckABCDEfunction is accessible as a function under ‘ss’ class and not under ‘ltipack’ package. It is not an object function and should not be called using an object of the ‘ss’ class.
Kindly follow the code snippet below to use the “checkABCDEfunction in R2024a.
A = [-1.5,-2;1,0];
B = [0.5;0];
C = [0,1];
D = 0;
sys = ss(A,B,C,D)
sys = A = x1 x2 x1 -1.5 -2 x2 1 0 B = u1 x1 0.5 x2 0 C = x1 x2 y1 0 1 D = u1 y1 0 Continuous-time state-space model.
R = ss.checkABCDE(A,'A')
R = 2x2
-1.5000 -2.0000 1.0000 0
