I'm not able to get the VolcFlow application working in Matlab. My instructions are below. I've set the path to the folder in which the files are held but on entering VolcFlow to the terminal I get the error "Unrecognised function or variable. Can someone help me please?
Use of VolcFlow
VolcFlow is writen with Matlab and is of very simple use.
Put VolcFlow.p and VolcFlowFig.fig in the same folder.
Type VolcFlow in the command windows and the following figure appears.

The error is simple and straight. You have not defined the variable z. Where is the variable z? It is in the file you have loaded. You need to define that variable.

When you load() a text file, and you do not assign the output to a variable, then MATLAB finds the basic filename (without directory information or file extension), and uses matlab.lang.makeValidName() on the file name to create a valid MATLAB variable name, and then assigns the content to the calculated name.
In your case with loading Caldera_Before.txt and not assigning the value to any variable, it would assign the content to the variable named Caldera_Before
