Hi
I have a 3-D matrix (A) of order a x b x c. And the data is recorded at 1056Hz sampling frequency. The data is already filtered between 0-5-10Hz, and epoched. I need to downsample my matrix to 65Hz.
Any help on how i can do it.?

Which dimension is time? That is, which is the dimension to be reduced?

It's the 'c'. The matrix A has 'features x chanels x samples'. e.g i have the data for 400ms, which is 480 sample, as in the data i have shared. :)

y = resample(A,65,1056,'Dimension',3);
