If-Elseif-Else Code to Switch-Case Statements for truth table

Hi, Following Enhance Code Readability for MATLAB Function Blocks and Enhance Readability of Code for Flow Charts I tried to generate the code of a truth table with Embedded Coder. However, I always get an If/ElseIf/Else statement. I tried to simplify my table (only 2 conditions), and then directly to use the chart generated by the truth table by integrating it in a Simulink Chart sub-function. I never get a switch statement.
How to do it right ? Thanks.

Not knowing your context, an if-elseif-else block is equivalent to switch-case-case-otherwise.
How to do this right?
How do you define "right"? What are you doing exactly? What are the available inputs and what is the wanted output?
I try to convert (1):
if (in == 1) {
out = 1;
} else if (in == 2) {
out = 2;
} else {
out = 0;
}
to (2):
switch(in) {
case 1:
out = 1;
break;
case 2:
out = 2;
break;
default:
out = 0;
}
With chart proposed above I get solution (1) only. I agree (1) and (2) are equivalent, but readability is improved in more complex cases.
You are mixing Matlab syntax with something that looks like either Java or pseudocode. You don't need a break in a switch (and it might even break a for-loop this might be nested in). Remove all curly brackets and add a closing end to make it valid Matlab syntax.
Also, like Jan, I don't understand what it is you want to do. So if this doesn't help, you'll need to explain more about your goals, possible inputs and desired outputs.
