/** @file rs_matrix.rsh
- * \brief Matrix routines
+ * \brief Matrix functions.
*
+ * These functions let you manipulate square matrices of rank 2x2, 3x3, and 4x4.
+ * They are particularly useful for graphical transformations and are
+ * compatible with OpenGL.
+ *
+ * A few general notes:
+ *
+ * \li We use a zero-based index for rows and columns. E.g. the last element of
+ * a \ref rs_matrix4x4 is found at (3, 3).
+ *
+ * \li RenderScript uses column-based vectors. Transforming a vector is done by
+ * postmultiplying the vector, e.g. <em>(matrix * vector)</em>, as provided by
+ * \ref rsMatrixMultiply.
+ *
+ * \li To create a transformation matrix that performs two transformations at
+ * once, multiply the two source matrices, with the first transformation as the
+ * right argument. E.g. to create a transformation matrix that applies the
+ * transformation \e s1 followed by \e s2, call
+ * </c>rsMatrixLoadMultiply(&combined, &s2, &s1)</c>.
+ * This derives from <em>s2 * (s1 * v)</em>, which is <em>(s2 * s1) * v</em>.
+ *
+ * \li We have two style of functions to create transformation matrices:
+ * rsMatrixLoad<em>Transformation</em> and rsMatrix<em>Transformation</em>. The
+ * former style simply stores the transformation matrix in the first argument.
+ * The latter modifies a pre-existing transformation matrix so that the new
+ * transformation happens first. E.g. if you call \ref rsMatrixTranslate
+ * on a matrix that already does a scaling, the resulting matrix when applied
+ * to a vector will first do the translation then the scaling.
