I have made a model in Simulink that contains a Matlab function block. When I try to use "cholupdate" I only get the following error: "Undefined function or variable 'cholupdate'."
Is it not possible to use cholupdate in a Simulink Matlab function (made for automatic C code generation)? I use Matlab R2013a and I can use cholupdate outside of Simulink.
"Chol" seems to work and I also get the help text for cholupdate in the editor.
If it is not possible to use cholupdate I would appreciate if someone could show me / post a link on how to implement it myself! I am looking for the Cholesky factor of then rank 1 downdate.
CHOLUPDATE is not supported for code generation. You can see an exhaustive list of functions which are supported here:
