I need to perform the conditions to the data file below on the matlab. can you help me how to do that.

Data File = 2x460800

Conditions:

1.) The scaling defined in the PhysioNet .info files for each PhysioNet data file was applied to each raw data file.

2.) The data were resampled to a common rate of 128 hertz.

3.) Each data file consisting of two ECG recordings was separated into two separate data records.

4.) The data length was truncated to a common length of 65536 samples.
