I don't believe there is a MATLAB function with that name. Is it presumably a user-written function. Look for a file called "randval.m". You can also type

>> which randval

to find the function, if it is in the path.

[Wayne King]

It is not a MathWorks' function. So apparently you have downloaded, or somebody downloaded, or has written a function randval(). If you enter

 >>which randval

You'll see where that function lives on your computer.

If you enter

 >>type randval

or

 >>edit randval

You can see the code. From the function name perhaps it is just picking one of the inputs (a or b) at random

Something like

   a = 2;
   b = 3;
   rval = rand(1);
   if (rval <0.5)
     a
   elseif (rval >=0.5)
     b
   end

I am only finding reference to it as a variable. What context did you find it in?

[Respaco]

In a Matlab program. something like randval(number1,number2)
