 * **`switch`**: output the value of one of up to ten input streams, according to the value of a selector input `which`.  Switch nodes can be of output type float, color<em>N</em> or vector<em>N</em>, and have five inputs, in1 through in10 (not all of which must be connected), which must match the output type.
-    * `in1`, `in2`, `in3`, `in4`, `in5`, `in6`, `in7`, `in8`, `in9`, `in10` (float or color<em>N</em> or vector<em>N</em>): the values or nodenames to select from based on the value of the `which` input.  The types of the various `in`<em>N</em> inputs must match the type of the `switch` node itself.  The default value of all `in`<em>N</em> inputs is 0.0 in all channels.
+    * `in1`, `in2`, `in3`, `in4`, `in5`, `in6`, `in7`, `in8`, `in9`, `in10` (float or color<em>N</em> or vector<em>N</em> or matrix33 or matrix44): the values or nodenames to select from based on the value of the `which` input.  The types of the various `in`<em>N</em> inputs must match the type of the `switch` node itself.  The default value of all `in`<em>N</em> inputs is 0.0 in all channels.
     * `which` (integer or float): a selector to choose which input to take values from; the output comes from input "floor(`which`)+1", clamped to the 1-10 range.  So `which`&lt;1 will pass on the value from in1, 1&lt;=`which`&lt;2 will pass the value from in2, 2&lt;=`which`&lt;3 will pass the value from in3, and so on up to 9&lt;=`which` will pass the value from in10.  The default value of `which` is 0.
