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)))

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).
