I have 39 alloys that each alloys my contain 7 elements Hf, Mo, Nb, Ta, Ti, V, Zr.
Is there any function or code in matlab to find is there any correlation between the atomic percent of these 7 elements in each of these alloys to the strength?
x1,x2,x3,x4,x5,x6,x7 are the inputs and the strength is the output.
you can see the attachemet for the data for these 39 alloys.
Best

It sounds like you want to plot the correlation between all pairs of variables.
If you have the Econometrics Toolbox, you can use corrplot().
If you do not have the econometrics toolbox you can follow this demo that shows how to recreate corrplot using plotmatrix.
Use readtable to import your data.
