Embeded existing C code in a Simulink model

I will appreciate if someone can show me some examples on very simple Simulink model which also embed the C code.

Answer 1

[William]

I consider myself a new user of Matlab/Simulink. I looked at some examples of "User-Defined Functions" but they were a little confusing to me.

Answer 2

There is an automated tool called the Legacy Code Tool which will generate a block that will interface with your C code.

Answer 3

[William]

Thanks. I am playing with example in the manual right now.

Answer 4

[William]

Is there any tool in Simulink libray you can embed the C code w/o using Matlab?

Answer 5

[William]

The example for Legacy Code tool only applied to one input & one output from the C code. Can we specify multiple inputs & outputs if my C code generate multiple outputs? Can I put mySF.SFunctionName = 'my_sfun_myccode'; mySF.OtuputFcnSpec = 'double y1 = 'myccode(double u1); mySF.OtuputFcnSpec = 'double y2 = 'myccode(double u2); etc.

Thanks.

Answer 6

[William]

One more question: The C code example in the manual has a function ("doubleIt") & returns one output. The C code I want to implement only has a for loop with multiple outputs. Do I have to create a function to accomodate my for loop?

Thanks in advance
