Yes, my data has a bunch of rows and columns and I want to find the mean of all the datapoints. I keep using mean(file_name) but I dont think that is teh correct mean.

You can not put file name into mean function.
Please put variable name which exist in your workspace after loading your data.
mean(variableName)
You haven't included your workspace in that screenshot so I don't see anything.
for example create a 5x5 matrix A and take mean value. Mean works with columns.
A = magic(5)
mean(A)

If you have R2018b, use the 'all' argument:
Avg = mean(MyMatrix, 'all')
otherwise, convert it to a column vector and take the mean of that:
Avg = mean(MyMatrix(:))
