Hi,

did you find a solution for this problem?

Thanks in advance,

Hi,

I solved this problem using this

function setup(block)

%% Register number of input and output ports
block.NumInputPorts = 0;
block.NumOutputPorts = 1;

%% Setup functional port to default
block.SetPreCompPortInfoToDefaults;

%% Setup output port
block.OutputPort(1).Dimensions = X;

%% Set block sample time to continous
block.SampleTimes = [ 0 0 ];

%% Register parameters
block.NumDialogPrms = Z;

%% Check Parameters
CheckPrms( block );

%% Run accelerator on TLC
block.SetAccelRunOnTLC(true);

%% Register methods
block.RegBlockMethod('Outputs', @Output);
block.RegBlockMethod('SetInputPortSamplingMode', @SetInpPortFrameData);
block.RegBlockMethod('CheckParameters', @CheckPrms);

%endfunction

I hope this will help you
