How can I efficiently pass variables from an m-file to a function in MATLAB?

[andrew.c]

Hiya,

I have been trying for hours to figure out how to pass a variable from an m-file to a function,

i could get it to work by making the variables global, but I've beeen told this is inefficient.

Any ideas?
Cheers!

Take a look at this Matlab tutorial, especially section 4-22. http://www.mathworks.com/access/helpdesk/help/pdf_doc/matlab/getstart.pdf

Perhaps I am misunderstanding the question, but you call the function in your main ".m" file (script).
Assuming your function name is "shift(input1, input2)", then it should be stored in "shift.m", (as it is a function, and they are typically stored in separate files). You call it appropriately with the correct function syntax. Remember in Matlab, you are passing copies of the variables into the function, like you would in C.
