Definition of function

Hi, I made a function to read data from Excel. I wrote this code and saved it as a .m file with the name of readExcel.m
function [a] = readExcel(filename) a=xlsread(filename); end
When I run the code I get this message:
??? function [a] = readExcel(filename) | Error: Function definitions are not permitted in this context.
What's the problem?
Thanks.

Are there any lines of code above the function definition line? That will generate that error message. For example:
filename = 'foo';
function [a] = readExcel(filename)
a=xlsread(filename);
end
In the Command Window:
>> readExcel('myfile')
??? Error: File: readExcel.m Line: 2 Column: 1
Function definitions are not permitted in this context.
A function file must contain nothing but that function (and any subfunctions below it).
As an aside: why make a function that just calls a built-in MATLAB function? Just curious.

Can you please do a direct, exact copy-&-paste of (1) your file, (2) the command you used to call it, and (3) the error message. You can edit your question and use the markup options to format your code as code.
