hello everybody..
i'm trying to make feedback from modelsim to simulink component and to pass the value to my modelsim component irrespective to time (with respect to a non-time variable).. So I used an embedded matlab function component from simulink that works based upon input flag coming from modelsim component.. at this point i 've alot of errors
- there is a variable that is passed from workspace to the embedded component, it carries a string representing the video name.. to do so it should be timed and to avoid that i defined it as a global variable but it does'nt work also..
- also i'm not able to use either aviinfo() or mmreader() within embeded component
- within embeded component i'm randomizing a value using randint() to avoid being absolete i used randi i got this error "Function 'randi' implicitly resolved in the MATLAB workspace. Implicit evaluation in MATLAB is not supported. Please declare this function extrinsic using eml.extrinsic('randi'), or call it using feval."
- beside that i'm having these errors -->Coder Error: Errors occurred during parsing of Embedded MATLAB function 'Embedded MATLAB -->InterfaceError :Embedded MATLAB Interface Error: Errors occurred during parsing of Embedded MATLAB function 'Embedded MATLAB
- plus this warning -->Chart Embedded MATLAB Function #18 has signals with underspecified type, size, and/or complexity.
- ONE MORE QUESTION plzz for any used variable within this block should i define it as persistant first or what as whenever i use a variable e.g. x_col = abs(round(x-(p_w/2))); got an error message asking me to declare it first
any help plzzzz
thanks

Niveen: Not sure what you mean. I though you already had a model with MATLAB Function block?
