Running MSC process in MATLAB

I am very new to Matlab, and do not have much experience using any sort of statistical computing software. I have been trying to run msc.m on a few data tables that I have, and haven't a clue how to input the data. Basically, my data is in a chart that has x values in the first column, then there are 15 samples in the 15 adjacent columns that would represent the Y values.

The program looks like this:

function [x_msc]=msc(x,xref)

% Multiplicative Scatter Correction

%

% [x_msc]=msc(x,xref)

%

% input

% x (samples x variables) spectra to correct

% xref (1 x variables) reference spectra (in general mean(x) is used)

%

% Output

% x_msc (samples x variables) corrected spectra

%

The file is in a csv format and I thought all i needed to type was msc('filename.csv') but it keeps on telling me there are not enough input arguments.

Any help would be greatly appreciated.

Cheers!
