MATLAB: Finding Corresponding Data at Events

eventsintervalstime

I have a matrix with data in one column and corresponding time intervals in the next column. Another matrix has event times. I am wanting to get the data from the first matrix that corresponds to the event time. I feel like this is simple, but I am having issues choosing the right way to go about this. The data is continuous so I want to make sure that I am getting a good approximation of the data when event times are between intervals.

There are only three rows that exactly correspond:
D1 = load('Heath Robinson Matrix1.mat');
D2 = load('Heath Robinson Matrix2.mat');
M1 = D1.Matrix1;
M2 = D2.matrix2;
[CommonTimes, ia, ib] = intersect(M1(:,2),M2);
DesiredResult = M1(ia,:)
DesiredResult =
      0.0027084     0.045775
      -0.083389      0.23977
       0.051537      0.25477
