How can I transfer variables From matlab code to simulink

I have a huge number of variables, some of them are data from excel, and I have all these information in matlab code (.m), how can I transfer variables to Simulink in order to work as we do with 'From-goto' blocks in Simulink?

I used 'from workspace' but it give some problems.

Thanks, I really apreciate your suport.

What errors do you encounter when using the 'From workspace' block?

I assume variables are loaded from the m-file. In addition to using the 'From workspace' block, you may also use the following methods:

1. Use MATLAB function blocks to achieve the same. You may find more information here: http://www.mathworks.com/help/simulink/slref/matlabfunction.html
2. Conversely, you may use Model Callbacks. To look at an example of how you may load variables from a MATLAB script (m-file) when opening a model in Simulink, follow this link: http://www.mathworks.com/help/simulink/ug/create-models-and-open-existing-models.html#btozflu-1.
