+* Filename: samples_to_rmlt_coefs.c
+*
+* Purpose: Convert Samples to Reversed MLT (Modulated Lapped Transform)
+* Coefficients
+*
+* The "Reversed MLT" is an overlapped block transform which uses
+* even symmetry * on the left, odd symmetry on the right and a
+* Type IV DCT as the block transform. * It is thus similar to a
+* MLT which uses odd symmetry on the left, even symmetry * on the
+* right and a Type IV DST as the block transform. In fact, it is
+* equivalent * to reversing the order of the samples, performing
+* an MLT and then negating all * the even-numbered coefficients.
