Function 'inv' is not supported in HDL coder.

i am trying to convert my .m file to vhdl using HDL coder. but while fix-point conversion function 'inv' is not supported. got a error " Function 'inv' is not defined for values of class 'int32' ". and in fix-pont converted file it converted with " fi_toint ". and fi_toint returns only int32 type. how do i fix this problem? any alternative to fix this problem??

The short answer is that the function call to inv is not supported by HDL Coder, just like the message you received says. The list of supported functions are available in the documentation at:

List of supported fixed-point functions for HDL Coder.

if you must have the behavior of inv in your HDL design you will need to write its behavior in MATLAB for the fixed matrix size you are working with.
