problem in calling a function, it does not recognize "switch case"

Please suggest the solution for the following problem. I am doing this in MATLAB 2021a. Thanks
I have three functions (1). function DSSK_Cons_Diagram = DSSK_Cons_Diagram_Gen(Nt )
(2). function DSM_Cons_Diagram=DSM_Cons_Diagram_Gen(Nt ,M)
(3). function DSMTConstellation_Mat = DSMT_Cons_Diagram_Gen(DSMT_SyS ,Nt ,M)
(1) and (2) works properly when I call them separately in the command window but the (3) has a problem it always says "unknown system". To call (3), I am writing like this,
DSMT_SyS =["dssk", "dsm"]; %DSMT_SyS is A string indicating the DSMT system for :
% −’DSSK’ for differential space shift keying ;
% − DSM’ for differential spatial modulation .
Nt=2,M=2;
DSMT_Cons_Diagram_Gen(DSMT_SyS ,Nt ,M)
The (3) is written here,
function DSMTConstellation_Mat = DSMT_Cons_Diagram_Gen(DSMT_SyS ,Nt ,M)
switch lower(DSMT_SyS)
case 'dssk'
DSMTConstellation_Mat = DSSK_Cons_Diagram_Gen(Nt ) ;
case 'dsm'
DSMTConstellation_Mat = DSM_Cons_Diagram_Gen(Nt ,M) ;
otherwise
error('Unknown system' )
end
end

Oh, okay, eq is short for equality, alright. Thanks for the info, it's quite helpful!

Most of the operators have a function associated with them that you can overload to overload that operator (for example, plus is the function you overload to customize how your class works with the + operator.) See the table on this documentation page for more information about the operators and their corresponding function forms.
