Before R2014b, I used to select Edit->Copy Figure in Matlab and then Ctrl-V in Word to paste (with the Copy Option being "Preserve information"). I define "best method" based on the quality of the picture when printed out on paper from Word (or PDF), clear not blurry. With new Matlab, this option gives poor quality when printed from Word to paper, especially minor gridlines, and especially when photocopied, compared to old Matlab. This option doesn't even work when the figure has many curves (several thousand curves with each curve containing about 500 points), neither doesas EPS. Save as BMP works, but quality is poor (raster vs vector).
