How to fit data to another data

I have two 1000000x1 vectors of data (data1 and data2). data1 is normalized. Now I need to scale data2 to data1.

You need to be more specific. What do you mean by 'scale'? Do you want to multiply a scalar to data2? Or each element of data2 needs to scale individually?

This is a more of a general question. I want to scale each element of data2 to data1. So the size of plot of data1 (i.e. the values in vector of data1) is proportional to data2 vector/plot. I have a variety of different data I need to work with. So my question is not case specific.

You can try something like this

x % the normalized array
y % the unnormalized array
y_norm = normalize(y, 'range')*(max(x)-min(x))+min(x)

It will make the min() and max() values of x and y same.
