I have A matrix like this:

A =

[100 0.35;

200 0.38;

300 0.40;

400 0.40;

500 0.42;

600 0.42;

700 0.42;

800 0.48];

My desired output is:

B =

[100 0.35;

200 0.38;

300 0.40;

400 0.41;

500 0.42;

600 0.44;

700 0.46;

800 0.48];

So what this B does is it check the data points to calculate where we have same values there it evenly distributes between these points. so for 400 data becomes to 0.41 (0.40+(0.42 - .40/2)) and for 600, 700 data becomes 0.44 and 0.46 respectively (0.42+((.48-.42)/3)*1) & (0.42+((.48-.42)/3)*2).

Is there any simple of way of doing it?
