changeSampleFreq

Easily change the sample frequency of a data-set

You are now following this Submission

dataNew = changeSampleFreq(dataOld, freqOld, freqNew, qFilter, qPlot)

This function gives the following output:
*The original data-set but with the chosen sample frequency

This function uses the following input:
*dataOld: The original data-set (as a column, multiple columns are possible)
*freqOld: The sample frequency of the original data-set (Hz [1/s])
*FreqNew: The desired sample frequency (Hz [1/s])
*qFilter (optional): Switch for application of data filtering (1 = yes), default is no filtering.
*qPlot (optional): Switch for creating a random plot of one of the data-sets
(columns) to serve as a visual check. Default is no visualization.
*qLastValue: adds the last value filtered if qFilter = true), default is false.
