how to resolve error for code generation

i have to convert my matlab code in C which will later used for my android application. i'm using matlab coder for conversion purpose. i'm getting error in following line

    load NaiveBayes
P_Class = predict(nb,A);

the error is:

 The output of a call to 'load' is not assigned to a variable . Assign its output to a variable without subscripting.
 Undefined function or variable 'nb'.

when i make changes to code as:

   S = load (NaiveBayes)
P_Class = predict(nb,A);

the error changes to this:

    NaiveBayes is not supported for code generation.
predict is not supported for code generation.

please help me in this case as i genuinely need to convert it to C.

S = load('NaiveBayes.mat');
nb = S.nb;
P_Class = predict(nb, A);

thank you so much Walter!!! but i'm still getting error for following line:

    P_Class = predict(nb,A);

as:

    predict is not supported for code generation

please please help me !!!!

It appears that it just is not supported. https://www.mathworks.com/help/simulink/ug/functions-supported-for-code-generation-categorical-list.html#btwz3ma
