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?

  1. replace the duplicated number with NaN or anything somehow.
  2. interpolate the data linearly
for duplication
unique
function may help.
for interpolation
interp1
would be a good fit for you.
