The real implementaion of the C2D function "Control Systems Toolbox"

Hello everyone,

I am trying to understand the differences between the discretization methods and therefore do my own implementation. However, when I get inside the function suing cntr+d, I get some unrelavent implementation that does not take into account the discretization method. Can anyone of help reach the real implementation of the c2d function?

Kind regards,

The function is: c2d() continous to discrete conversion

The non-complete implementation:

Hi Youssef,

There are two files named c2d.m

which -all c2d

/MATLAB/toolbox/control/ctrlobsolete/c2d.m
/MATLAB/toolbox/shared/controllib/engine/@DynamicSystem/c2d.m  % DynamicSystem method

I believe the code listed in the question is of the former. The latter can be opened in an editor, at least in R2022a, and one can set a breakpoint and step through the code using the debugger.
