File naming based on user input

So, I've got some code begins :
function [ Output ] = flatlandprojection(y)
and ends with
put=transpose(Output)
xlswrite('fileout',put);
end
with some coding mcjiggery in between that produces "Output".. I wondered if there was a way to allow for user input in the function that would determine the name of the created file...
I'm imagining something like... function[Output] = flatlandprojection(y,"desired name") such that this results in .. xlswrite("desired name",put);
as things stand, I have to change the file name by changing the code for the function itself, which feels crumby.
Thank you in advance. I really appreciate all the help I've received from members here.

function [ Output ] = flatlandprojection(y, filename)
...
xlswrite(filename, put);

I tried that, as it's quite similar to what I imagined. Unless I'm doing something wrong without realizing, I find that that does not work: "Undefined function or variable 'filename'."
It seems like I need to get the function recognize the input as pure text, so that it doesn't try to interpret it. I'm not clear on the syntax required to make this work.

"I'm not clear on the syntax required to make this work."
The syntax is exactly what Walter Roberson showed you. It will work when you supply the name string as the second input argument to the function when the function is called:
y = ...
name = 'MyFile.txt';
z = flatlandprojection(y, name)
Basic MATLAB useage, such as how to call functions, is covered in the introductory tutorials:
