Benoit Jacob	c3180b7ffb	MatrixBase: ... * support resize() to same size (nop). The case of FFT was another case where that make one's life far easier. hope that's ok with you Gael. but indeed, i don't use it in the ReturnByValue stuff. FFT: * Support MatrixBase (well, in the case with direct memory access such as Map) * adapt unit test	2009-10-20 23:25:49 -04:00
