how do you set @synthesize for an array?

Hello. How do you set @synthesize for an array like: float rgb[3]. Also, is the @property line: @property(nonatomic, assign) float rgb?? Thanks

From stackoverflow

• I don't believe that you can define the array size in the interface if you wish you use it as a property. You would need to do something like: (pardon any syntactical mistakes, this is from memory)

  @interface MyClass : NSObject {
      float *rgb;
  }
  
  @propery (nonatomic, assign) float *rgb;
  

  Then in your implementation:

  @implementation MyClass
  
  @synthesize rgb;
  
  @end
  

  Then you would have to initialize the pointer using some C functions, such as:

  rgb = (float *)malloc(sizeof(float) * 3);
