I have a very large set of data of over 1000 readings in [A]. I need to reduce the data to 101 readings evenly spaced over the original data set. Can anyone give me some help, or point me in the right direction? Any help would be much appreciated.

If DAT is your original data.
NewDAT = DAT(round(linspace(1,length(DAT),101)))

The DAT is a (3529,2), when I do what you suggested it gives me a (101,1). My data is (T,R) matrix as in readings vs time. What I need is 101 samples of the data with the time and the value associated with the time. I am new to MatLab, only been working with it for a few months so I not know a lot of the functionality of it.

NewDAT = DAT(round(linspace(1,length(DAT),101)),:)
Indexing in MATLAB is A(row,column). Using : in place of column gives all columns (for the specified rows).
