Would it be appropriate to use this kind of logic in Matlab? I am getting a weird slope graph so I wanted to double check.
From this graph ex:
plot(strainpercentage(452:502),c3(452:502))
To find the slope, this plot:
plot(c3(452:502)./strainpercentage(452:502))

Use gradient of diff to determine the slope.
plot(diff(c3(452:502))./diff(strainpercentage(452:502)))

Great, that makes more sense. Thanks
