Simulink reading mat file issue

I have recently created a model to capture a large array of data to mat file in the simulink environment. I used from 'mat file block' to extract my mat file to my scope where the output data type uses my busdata objectin order to extract data regardless of data type.
I get two error messages:
Error encountered while reading from my mat file.
Non-infinite data, Nan, inf or -inf are encountered while reading from file.
Your assistance would be greatly appreciated.

Some of your data are equal to nan, load your mat file, make interpolation to replace those nan values, and save again your new data in a mat file

Thank you for your advice but I am a bit puzzled why nan inf or -inf data appeared in my mat file when most of my data are in double format which I expected my data should not have Nan inf or -inf.

Check your data in Matlab windows command
load yourfilename
% If y is your array, use
find(isnan(y)) % check for nan numbers
I have tried to run what you suggested and I get Empty matrix 0 by 1 for every data array.
Then probably your array has Inf in it. You can check it with:
find(isinf(y)) % check for nan numbers
