How to switch between two different functions

I am trying to write a function in which i can switch between two different functions called linear & joint, both are an array of six. Now the function only needs to switch when the linear or joint arrays are unchanging. I was thinking about using the switch functions and placing cases but didn't know how to quite implement it. Can anyone help?

It does sounds like a switch statement is what you need. I did not understand what you meant by "when the linear or joint arrays are unchanging". Also, I am a bit confused when you say that are functions, but also they are an "array of six". You might want to lay out a bit more detail. Finally, if there is someone who might be able to help you with the English, that might help, too.

Ok what I meant was that both the linear and joint function will produce an array of six. So when the output of one function is unchanging the script should switch the current function to the other function, which is dependent on whatever one of the two functions are being used.

   switch whichFunction

      case isLinear
          y = linear(x);

      case isJoint
          y = joint(x);

   end

Thank you Rick...could you please provide some comments with this script? Thank you much appreciated :)

What questions do you have?

Perhaps

case 'isLinear'

and

case 'isJoint'

would be clearer for this purpose.
