Using matlab to seek minimum value from data file?

Hi

I'm pretty new to Matlab and can't figure out a couple things to let me plot my data. I have several data files showing the same thing at varying temperatures. My goal is to plot the values of x=0 minus the minimum value wherever that is and make a Delta-y vs temperature plot. Is there any way i can get matlab to seek and plot the minimum value of y from a data file?

Read the data file. apply min() to the data you read in. subtract that value from your data.
