Hello all, I want to pass a string into a Matlab function block.
This string is a mask parameter that must not be evaluated (it's a name). I'll try to pass it via a structure like this:
function Out = GetDiagAvail_mf(structArg)
coder.extrinsic('disp');
Out = coder.nullcopy(uint8(0));
disp(['in EML code, varName = ',structArg.varName]);
Out = coder.ceval('MyFct',coder.opaque('const char *',structArg.varName));
structArg is built in mask Initialization Pane like this: structArg.varName = Param;
'Param' value could be: 'MyString'.
I want to have in generated code: MyFct(MyString);
But I have this error:
_Error c2_lib_DSM.c: 161 undeclared identifier `MyString'
Warning c2_lib_DSM.c: 161 possible usage of MyString before definition
Warning c2_lib_DSM.c: 318 static `void function(pointer to void,pointer to const incomplete struct mxArray_tag defined at C:\Program Files\MATLAB\R2011b\extern\include\matrix.h 299,pointer to const char,pointer to void) c2_c_sf_marshallIn' is not referenced

1 errors, 3 warnings
Please, can you help me?
I'm using Matlab 2011b.
Thanks in advance,
Ursula
