how to Specify the arguments of imfilter in codegen function ? how to call it with the right parameters ?

Hallo everybody,

i'm trying to optimize the run time of my App by getting imfilter function called as a C Code .

so first i used the following codegen code to creat a the C Liberies :

codegen -d imfilterlib -config:lib imfilter -args {zeros(3456,5184,'double'),zeros(399,399,'double')}

so im not sure if the input arugments here are the right one, for an Array 3456 x 5184 class double for the first argument for example.

the filles are generated and saved with out any problem

now when using coder.cval function calling the generated function comes allways the error that coder.cval function is not supported in Matlab.

coder.cinclude('imfilter_initialize.h');
               coder.cinclude('imfilter.h');
               coder.cinclude('imfilter_terminate.h');
               coder.ceval('imfilter_initialize');

as showen in the screenshot :

is it something to do with the matlab version i did somthingwrong using the function. i would be very thankfull if you can help.

thanks a lot.

best regards
