Arouna Kone's quickfire double at the end of the first half gave them an advantage they quickly made decisive after the break when Maynor Figueroa combined with Franco Di Santo for the defender to net a rare goal.
"We are disappointed with the points tally that we have got. We need to get more points on a consistent basis," Martinez said.
"Today we came into a game which is a massive, massive relegation battle I thought we were composed and able to enjoy our football.
"We limited Reading to no shots on goal in the game and that is a real compliment.
"The quality of our attacking play was also a real difference.
"We've been showing that this season but we've never had that clinical way of defending and keeping a clean sheet. That's why I am so pleased with the performance."
