Vector dimensions and variable display

Hi This is a question about how Matlab displays certain variables, depending on the number of dimensions contained. When I generate randn(10,2), I get a 10X2 table in the workspace window, very easy to copy paste directly from here to excel. However, when I do randn(10,2,1), Matlab creates something that looks like a text file in the workspace. Copying the data over can be a pain when you have randn(1000,2,1) for example. Why does Matlab do this?
For context - I want to "pre-generate" (if there's such a word) a set of random numbers for multiple assets and for multiple simulations; hence I'm using randn(NumSteps,NumAssets,NumSimulations). Thanks C

Instead of copy-and-pasting, why not just get MATLAB to write the Excel file for you?
"Copying the data over can be a pain when you have randn(1000,2,1) for example. Why does Matlab do this?"
Because data is reliably written to files and read from files using the appropriate functions. Copy-and-pasting is not a reliable method for transferring data between files/programs/applications/...

Thanks sir - coming around to that way of thinking.....and going to implement that.
