I have attached an example.
The second computation in the example, producing "WC", has no basis in any physics; I just needed to put in something to show that the code worked.
To use: carefully click on the red bar of one of the two sliders and drag it. When you have both positioned as desired, click Run and observe the (useless) answer.
You might be able to use the same kind of slider style that you used in your code; the important part of the example is that the sliders are adjusting the parameters of constant blocks and the blocks are then acting as input signals.

In the designer use writeFIS to create a fis file. Do this ahead of time in a separate session.
In the Fuzzy Logic Controller block specify the name of the fis file
When you use Simulink to generate for a target, Simulink will read the fis file and will generate code that will load in appropriate data structures. You will not need to add any code to read a mat file.
Note that at the time the model is generated for target, the content of the file will be locked in to the model. You will not be able to tune or revise the rules in the deployed model, not without rerunning the deployment process.
So you need an interactive matlab session (with appropriate licenses) to build the fuzzy model. The deployed model is stand-alone and does not need any license to run (so go ahead and copy it to all of your embedded systems), but the flip side is that you cannot adjust the FIS rules in the deployed models.

a = 123; b = 456.789;
whos % variables a and b are displayed
save test.mat
clear all
whos % nothing is displayed
load test.mat
whos % variables a and b are displayed again
