Error evaluating 'InitFcn' callback of block_diagram 'MIMO_OFDM_' Undefined function or variable 'MIMO_parameter'.

Hi all,

I get following error while executing the simulink model,

Error evaluating 'InitFcn' callback of block_diagram 'MIMO_OFDM_VBLAST'. Undefined function or variable 'MIMO_parameter'.

i tried to do right click on an empty spot in the model and select Model Properties; and tried to go to the Callbacks tab .

But i can ´find only block properties when i do the right click and when i see the callbacks tab it is idle' i cant view or edit the callbacks tab.

Note: The block is a Random Integer generator block from the communication block set and i am executing the model in xilinx system generator configured with the simulink.

I would appreciate if any one could help me to remove this error.

Regards,

Rahul

Is the inability to access the Callbacks tab specific to the Random Integer generator block, or are you seeing the same issue with other blocks from the Simulink Library as well?

i solved the issue, i jus right clicked on the empty space of my model and i got the option model properties.

i went to call back option panel and gave the right path of m file in the initfcn panel. thanks for the interaction.

the real reason is the ubication of the files, everything should be on the working directory..

@rahul, can you please explain what you mean by the "right path of the m file"? Which file are you talking about?

Since I shut down matlab improperly, I got the same problem.

My solution is setup Cmake configuration again, and it works.
