MATLAB Analyzing Wall Thickness vs Force Data Sets

AI Thread Summary
The discussion centers on the challenge of synchronizing two data sets extracted from a .CSV file and an .mdb file for analysis in MATLAB. The first data set represents 'Wall Thickness vs. Time' over a time interval of [3400 - 8200] seconds, while the second data set shows 'Force vs. Time' over the interval [38000 - 38600] seconds. The objective is to demonstrate a correlation between wall thickness and drag force, with the expectation that increased wall thickness correlates with higher drag force. However, the primary issue arises from the differing time formats, making synchronization difficult. The question is raised about the expectation of synchronization given the significant difference in time intervals between the two data sets.

Attached are three figures. The problem in question essentially involves extracting data from a .CSV (MS Excel) file and .mdb (MS Access) file which I have done already but not correctly.

Data set #1: gives me 'Wall Thickness vs. Time' ( [3400 - 8200] s , [0,1] in.) as shown in figure3.jpg.
Data set #2: gives me 'Force vs. Time' ( [ 0 - 17,000] lbs. , [3.8x10^4, 3.86x10^4] s) as shown in figure2.jpg

figure1.jpg is the figure that plots both at the same time. In the Wall Thickness vs. Time graph, I had only selected the first step function within figure3.jpg.

Physically we expected that higher wall thickness requires higher drag force. The idea is to prove this correlation.

The issue is with the time format in MATLAB. I cannot synchronize them together.

I hope that is clear.

Thanks for your help,

One data set is measured over the time interval [3400, 8200] whereas the other is over the interval [38000, 38600]. Why would you expect them to be synchronized?
