What are some ways of normalizing my data with MATLAB?

I have a series of concentration transients that go from 0 to 0.5s, but the problem is they start at different y-values and there is some noise in the data. They rise exponentially and plataeu and have roughly the same amplitude. I want to normalize them appropriately so that where they start on the y-axis is the same. How can I do this with MATLAB without introducing too much error?

Let x (a vector) be your data.....you can normalize your data as below:

z = (x-min(x))/(max(x)-min(x)) ;
