How to find linear correlation and how to add a horizontal average line when the dimensions of arrays being concatenated are not consistent?

B4= (151.4 150.2 142.2 152.8 152.2 150.1 152.3 150.1);

B5= (547.1 548.5 548.1 544.4 531.5);

This isn't paired data. Which data should correlate with which?

[Kofial]

B4 and B5 should correlate together. The numbers are just to show the size. They can be different. Like for example: B4= (151.4 150.2 142.2 152.8 152.2 150.1 152.3 150.1); B5= (151.4 150.2 142.2 152.8 152.2 150);

They are not paired, so they don't correlate. The whole point of correlation is that you have pairs of numbers and you can try to define a trend.

How would you do this with pen and paper? That may help us to understand what you mean and how you could implement it in Matlab.

[Srivardhan Gadila]

In order to find the linear correlation between B4 and B5 they should have same number of observations/ elements.

Please refer to corr for more information.
