So I have a graph of glacial melt per year and it has 169 variables. I need to know the difference between each point. For example on excel you do b-a=# c-b=# d-c=# and so on down the list. I have tried a few different ‘solutions’ for writing this code but it never works. Please help

See the diff() command.

"Every time I try this command it tells me there are too many variables..."
That is because using 169 individual variables is the wrong way to use MATLAB. That data should be in one variable. Then processing and handling that data would be trivial (e.g. you could simply call diff on it).

Before using an unfamiliar command, you should read its documentation to learn its proper usage. In this case, you can see in the documentation for diff that there is no input syntax allowing 169 separate input arguments.
