#### 8.2.48 scalarexpand ¶

Function: `[out1, out2, …, outN] =` scalarexpand `(x1, x2, …, xN)` ¶

  Expand scalar inputs to match size of non-scalar inputs.

  Expands each scalar input argument to match the size of the non-scalar input arguments, and returns the expanded values in the corresponding output arguments. `repmat` is used to do the expansion.

  Works on any input types that support `size`, `isscalar`, and `repmat`.

  It is an error if any of the non-scalar inputs are not the same size as all of the other non-scalar inputs.

  Returns as many output arguments as there were input arguments.

  Examples:

      x1 = rand(3);
      x2 = 42;
      x3 = magic(3);
      [x1, x2, x3] = scalarexpand (x1, x2, x3)
