In case of support vector machines(both for classification and regression), the score function/regression function might not be in terms of input predictors, hence it might not be possible to get the regression function. The coefficients can be obtained using
trainedModel.RegressionSVM
As a workaround, you can use other regression techniques such as linear regression, which derive output in terms of predictors.

You can export the model, and create a function that takes in a value, calls the predict function, and returns the output. Then call this function from excel using matlabfcn.
If you need further help, feel free to create a new question, as that would reach out to more people.
