Prev: why does my s-function run so slowly?

I am having a problem plotting data, it seems that the data I want to use isn't sorted. I have 2 columns of data; y,T. I can load the data file into Matlab but is there a way i can sort the data based on y? It is crucial that the y(1) stays with T(1) and so forth.

thanks

doc sort

sort, then use logical indexing

Or use sortrows()
