Hello,
I have created some plots that show information about the number of cells and the size of the cells. On excel, the data looks like this:
The blue line is the count, the orange/gold line is the size.
From a plotting perspective, the count data is as follows:
x1 = [1 2 4 6 8 10 11 14]; y1 = [1 1.5 2 1.5 4.333333333 1.5 1.5 1];
the size data is as follows:
x2 = [ 1 2 4 6 8 10 11 14], y2 = [72.49283 80.96316 228.9255 60.36849 66.8786 88.73138 328.6935 78.67592]
I would like to create a function for both of the data sets, and then also create a function which describes both sets of data. How would I go about doing this?
Thanks for your time.

What do you mean by "create a function"? Do you want to be able to interpolate the datasets?

Curve Fitting Toolbox should do what you want. See the attached figures to see how to get it done.
To import those fitted models to workspace, go to Fit->Save to Workspace.
