When you are using MATLAB function block, you need to carefully adjust data types. MATLAB works naturally with all doubles. You can either use the data type conversion block listed above by Hyunuk, or you can control MATLAB function interfaces using the Ports and Data Manager from the MATLAB function block toolstrip.

Additionally you may need to reassess the operation in your MATLAB function and eventually "cast" the data type in your operations, such as a = x * double (b)
